The whole country's industrial software fever seems to have finally found the lifeblood of industry. But looking at the past, it is still an illusion. At present, the revitalization of industrial software is like the routine of "throwing Hydrangea to choose bridegroom". It is very lively and the number of places is limited. Only a few lucky people can be noticed. This approach is completely incompatible with the colorful industrial ecology of industrial software.

Industrial software comes from the needs of manufacturing and is inseparable from industrial products. Therefore, it is as vast as the sea as industrial categories. In this vast deep sea, there are big heads with an output value of more than $1 billion. It seems that there are all kinds of software, just like great white sharks and humpback whales - including Dassault system, Siemens industrial software, ANSYS, Synopsys, etc; There are also some head stars who fight alone, such as CAD / CAE / EDA software. With a little attention, they can recognize these seals and octopus, such as French ESI simulation, American MSc and Altair, as well as dipler, Guangzhou Zhongwang and Suzhou HaoChen under Fujitsu of Japan.

However, more industrial software is deep-sea species. Rich and colorful life needs deep sinking to see its beauty. It is these quiet, unknown creatures that secretly rule the ocean in another way. At present, the well-known commercial software is only a lively corner of the ocean.


Every part is inseparable from software  
 


Speaking of these ubiquitous software, we might as well start with the automotive industry. Automobile is a model of large-scale industrialization. It is not surprising that industrial software is extremely prosperous here. As early as when CAD / CAM was just budding, in addition to aviation manufacturing, the automobile industry was the best cradle.

In the field of automobile design and R & D, general CAD and CAE software have been widely used, needless to say. In addition, there are many hidden industrial software lone wolves, which are not easy to be known by outsiders.

Let's start with the most important power plant: the internal combustion engine. As an independent company in the development and test technology of automotive powertrain system, Austrian AVL should be a guest of all engine manufacturers. China is undoubtedly one of the countries with the deepest roots with AVL. Its founder once taught at Tongji University. After returning home, he established AVL company in 1948. Its good relationship with China also makes it benefit a lot with China's automobile becoming a big manufacturing country. Various AVL devices can be seen in the R & D centers of many domestic automobile manufacturers s. The price is also unambiguous. A set of emission detection equipment is often tens of millions. There are many software under AVL. For example, as a professional engine flow mechanics software, AVL fire can simulate and analyze the combustion inside the engine in detail. At the same time, it is equipped with tail gas post-treatment module, which is used for the research of various catalytic converters. These software, nurtured by the experience of a large number of automobile users, have high reliability and skilled interface, so users have a high degree of dependence.

In the current era of internal combustion engine, it is being seriously challenged by increasingly popular electrification and increasingly stringent environmental protection regulations. So are these internal combustion engine software helpless?

The answer is just the opposite. These software companies from the front-line engineering field just reflect its unique sensitivity here. As users turn, so do these companies. The electric drive software eSuite of AVL can complete the design of electric drive assembly, and has good adaptability to the roar of gearbox and motor rotor. In fact, the functions of these software are no longer limited to ice itself ("fully flexible internal combustion engine"), but distributed on the whole power system ("fully flexible power system"). By balancing the complementary characteristics of electrification and internal combustion engines, synergies can be generated in reducing emissions. It can be said that in the era of electrification and electronic control, the application of software is equally handy. AVL's current software direction also covers new areas such as autopilot systems. It is such a company with a global turnover of nearly 2 billion euros in 2019. It can probably be ranked within the top 400 of China's top 500 machinery manufacturers. Chinese automobile is completely inseparable from its equipment and software.

For such a large market of automobile manufacturing industry, it is difficult for any enterprise to eat alone. In addition to AVL, there are three major engine design consulting companies in the world: FEV in Germany, Ricardo in the UK and Southwest Research Institute in the United States. These design consulting companies have the engineering advantages of integrating software and hardware. Because these institutions often have a very good engineering consulting background, they have long become close advisers to automobile manufacturers rather than simple software providers. Software is a prominent feature. For example, the internal combustion engine simulation / analysis and design software of Ricardo Ricardo software is also a regular passenger of cars. Ricardo ignite is a complete vehicle system modeling and simulation system, including drive cycle, performance and thermal system analysis.

The engine fluid simulation software converse developed by American CSI company is also used by foreign main engine manufacturers. Compared with the complex meshing of classical software such as star CD and avlfire, it has unique highlights in meshing, such as adaptive mesh refinement, chemical reaction kinetic combustion model, etc. It is not surprising that such software can be loved by academia (domestic universities and combustion laboratories). The company was also founded by a graduate school of an American University. At first, it was just a CFD consulting company. Later, the engineering experience knowledge was solidified into software, and it began to enter the field of fluid analysis software in 2008.

From the perspective of the development strategy of vertical industry software providers, in the face of huge industrial software giants, single point breakthrough is a more effective tactic. It's easy to fail if you want to challenge giants directly and comprehensively. Therefore, even if the technical performance is good, users may not buy it. The formation of user habits is a long process, which is by no means a distance that can be made up with money in a short time. This almost suffocated the growth space of latecomers.

   


Table 1 common vehicle simulation software

Cars need a lot of industrial software. In this small mobile castle, all kinds of devices that can be counted are soaked in software. To make passengers feel comfortable, car air conditioning is not a small thing. Various engineering optimization are essential, such as pressure loss, noise minimization, chemical reactor mixing efficiency maximization, etc. Sculptor provided by American optimal solutions software company is to provide real-time deformation technology based on arbitrary shape deformation to help designers solve the shape optimization problem of air conditioning pipes. Because 3D data can be reused, even if the mesh is redrawn and the model is constructed, the design does not need to be modified. This saves designers a lot of time. The seseus-fe developed by German PZ engineering company is an air conditioning system for aerospace and automobile cockpit, which is specialized in thermal comfort analysis. A fighter cockpit also has complex engineering considerations. It needs to consider the driver's comfort from ergonomics. The parent company of PZ company is a strange combination of European groups, including engineering software and tooling system. It was acquired by Mitsubishi Chemical in 2018. Among various industrial categories, industrial software is the most hidden. The court is as deep as the sea, hidden and hidden, distributed in one extremely small circle after another.

The automotive industry generally uses the software and hardware of German dSPACE company. By customizing the code, you can seamlessly connect the software and hardware, quickly build the prototype, and integrate the three complete working processes of model in the loop, hardware in the loop and system simulation. But this kind of software and emulator are very expensive - tens of millions of yuan, which can only be enjoyed by automobile enterprises. Since German Volkswagen has been used first, forming a good demonstration effect, domestic FAW, Chery and Yutong are all in use. It also has a great impact on other fields such as aerospace, power electronics, fans and so on.

If we continue to subdivide, we can talk about the hottest power battery now. There are at least 10 kinds of software for electrochemical simulation of photolithium battery. For example, the performance analysis software GT autolion of gamma company of the United States, taufactor based on open source matlab application, battery performance and cost model batpac software, etc.

From the perspective of Dali, autopilot is undoubtedly a place where heroes compete. In order to obtain sufficient security verification, simulation test services of billions or even tens of billions of kilometers are often required. In the actual test process, due to the slow efficiency of real road test, many car companies tend to choose automatic driving simulation test. It is said that 90% of the automatic driving test will be completed through simulation, 9% through the test field, and only 1% will be carried out on the actual road. Since the intelligent network is the focus of the future automobile, there are naturally heavy troops in the simulation industry. Including simulation platform (VI grade), scene simulation (such as Esi's Pro sivic), dynamics (SIMPACK), vehicle networking simulation (vsimrti developed by dcaiti, Daimler Automotive Information Technology Innovation Research Institute, Germany), hardware in the loop (such as Ni), thirty or forty kinds of software products gather in this newly developed virgin land for intensive computing bombing day and night.

Although Germany's achievements in large-scale general industrial software are not great (except that Siemens has acquired a large number of industrial software), it has made great achievements in vertical industry software with the help of strong industrial force. Founded in 2005, German VI grade company, relying on the advantages of German automobile industry, provides vehicle driving simulation system for vehicle dynamics simulation, software in the loop, hardware in the loop and human in the loop simulation test, which greatly reduces the physical sample vehicle.

The German dSPACE real-time machine, which is also widely relied on by the Chinese automotive industry, mainly does electronic control unit and hardware in the loop analysis. Although it was banned from China's military industry as early as 2008. But the auto industry is still liberalized. For a long time before a new model goes on the road, automobile manufacturers and their suppliers need to use dSPACE end-to-end solution to test the software and hardware components of new vehicles.

In fact, it is unimaginable for industrial software to pursue comprehensive autonomy. Taking the automotive industry as an example, software needs modeling, simulation and code generation software systems, including system modeling MATLAB of the United States, LabVIEW of Ni of the United States, electromechanical and hydraulic multidisciplinary modeling tool Dymola of Dassault of France, simulation X of ITI of German engineering company, and powertrain simulation and analysis software cruse of AVL, while hardware needs real-time computing equipment, such as dSPACE of Germany, Ni of the United States RT-LAB of Canada, etc. These foreign related software and hardware manufacturers form a similar Wintel alliance and almost control the high-end development technology system and means of complex system products. Taking the field of automotive electronic control as an example, AVL Liszt's engine design and analysis software, coupled with the German real-time computing equipment dSPACE, has both soft and hard, almost monopolizing the forward design and R & D technology system of automotive electronic control in China.


Become a delicacy for equipment manufacturers  
 


Machinery manufacturing is a rich mining area of software. Dig down one by one, and the software will emerge one by one. Mechanical transmission is a huge category, and gear is the most common subclass. However, gear is a key basic part with large quantity and wide range, and has become the largest industry in China's mechanical basic parts. In 2018, the output value of the national gear industry exceeded 240 billion, ranking first in the world. Such an industry is naturally inseparable from the figure of software.

To say precision, from luxury watches to missiles, the precision mechanism behind them is inseparable from the design of gears. Since Switzerland is famous for precision watches and precision machine tools, it is not surprising that Switzerland's gear transmission software. The tool software for mechanical parts design and transmission system analysis developed by kisssoft, Switzerland, is a leader in the industry, which can design fan gears, etc. However, these two software have been acquired by Gleason gear machine tool company.

Gleason's machine tool is one of the few rare surviving varieties in the American machine tool industry. It has always been famous for processing precision gears and transmission systems. Many domestic automobile gearbox and steam turbine are its users. It is also one of the suppliers of U.S. arms dealers and maintains a good relationship with the U.S. Department of defense. This is also a feature of American machine tools. Many small processing machine tools have been transformed into machine tools specifically aimed at the American arms business. Business is still doing well.

It is conceivable that Gleason also has a set of gear software, which is an important guarantee for it to provide transmission solutions. Through mergers and acquisitions, one high-end, one medium and low-end, and the organic combination of the two, Gleason company has achieved comprehensive coverage in CAD / CAM of cylindrical gears, bevel gears and their shafting parts. CNC machine tools must rely on software to realize motion control. It is the organic combination of this software and machine tool body that forms Gleason digital gear manufacturing system. The relationship between Gleason's machine tool and gear software is just like the relationship between computer and software. Without the support of software, it is difficult for machine tool to process gears with high precision and high performance.

This is also the most vulnerable place in China - whether it is software or equipment. First look at the software. There is also an enterprise specializing in gear software transmission in Hunan, which can provide software and solutions for all kinds of gears. However, due to the lack of scale, we often can only adopt the way of project customization; Looking at the equipment, Qinchuan machine tool, an old brand factory in the west of China, has been biting its teeth for many years, following the American Gleason machine tool, all the way through the standard. There are also private enterprises that have sprung up in recent years, such as Zhejiang tuoman, which is benchmarked with Mitsubishi gear hobbing machine, have also made great progress. But if the gap is still visible in the era of machinery and numerical control; Then in the digital age, the gap becomes hidden and immeasurable. Because the equipment must rely on software in order to play a more excellent performance. However, this is still only a superficial phenomenon. As we have seen in many places, behind industrial software is mathematics, physics and engineering, which is its muscles and bones; It programming is just the last thing it has to wear. The reason why the software of Gleason gear machine tool is powerful is inseparable from its mathematical foundation. Gleason has many mathematicians who are very accomplished in gear theory, which is the fundamental reason why it can become the king of gear surface machining.

The concept that software is inseparable from machines must be melted in the blood of enterprise operation for the Swedish haxacon measurement group, which started from CMM. Sweden hexcon has acquired hundreds of software companies, and recently acquired UK romax software, focusing on the field of wind power, which is the virtual prototype design and analysis of gearbox, bearing and gear transmission. The computer-aided manufacturing CAM software Esprit acquired by hexcon at the end of October is shocking again. Esprit is well-known for its machine optimization and no need to edit G code (tool path). However, six years ago, when hexcon acquired Vero, which ranked first in the global CAM software, it suddenly grabbed a large number of CAM software, including Edgecam and worknc commonly used in machine tools, as well as radan software specially used for sheet metal processing. Then, a manufacturer of measuring instruments has been constantly acquiring and acquiring software. How much software does it need to be satisfied? Perhaps the demand for quality is endless, and the demand of machines for software is endless.

The reason why this M & A is particularly shocking is that it is a serial cannon. Because in the same month, Sandvik clonon, the world's first tool manufacturer and also a Swedish manufacturer, bought CGTech of cam simulation company. Tool company and CAM software are good partners of well water and river water. This time, CAM software was eaten by tool manufacturers. Moreover, both cam companies are located in California, USA, with sales of RMB 200-300 million in 2019. If you have good software, you'd better take it. This is the attitude of foreign machine manufacturers towards cam.

CAM software used to be a very independent software field, which is very important for the operation of NC machine tools. Nx (UG), the most famous brand in Siemens industrial software, started from cam. However, in recent years, independent cam software manufacturers have been heavily acquired, and the brands have decreased rapidly. This also makes this software more valuable and hidden.

However, such roar and thunder is not enough to awaken China's manufacturing industry. The war of Intelligent Manufacturing in China, It has burned into another "intelligent" battlefield. Up to now, one of the most vulnerable places of China's intelligent manufacturing is to turn a blind eye to CAM software. This is where foreign industry 4.0 or intelligent manufacturing makes efforts. CAM software is inseparable from making good use of machine tools and improving the flexibility of machines. Germany has support in this aspect every year, but it is almost forgotten in China.

There are too many CAM software acquired by hexcon. If the troops are arranged, it will be as lively as the romance of the Three Kingdoms. The formation of the five tigers general will be arranged. Zhang Fei, Zhao Yun and Guan Yu, Huang Zhong will arrange the formation together. In China, if it does not rely on the support of Beijing precision carving machine tools, it will almost be an empty city plan. This machine tool company, which started with CAM software, should be the most successful example of the combination of software and hardware in China's machinery manufacturing field. Many people attribute the success of Jingdiao to seizing the opportunity of the rise of the consumer electronics 3C market and getting close to Apple's spacecraft. In fact, the rise of smart phones has brought many machine revolutions. This great wave of momentum provides equal opportunities for many eager people. But Jingdiao got the ticket in the most favorable position, which is closely related to its cam software that has been polished for many years. The moment when there was no light and no future was the most familiar suffering of every founder of industrial software. However, as long as you get through it, there will be great returns. At present, industrial software is frequently bringing good news to machine manufacturers.

Hexcon is not alone. Zeiss of Germany acquired 3GO, a software and hardware supplier of measurement technology, last year. If you want to understand the changes brought by software to hardware equipment, it is very representative to compare renishau, who is also a metrology background in the UK. Renishaw is weak in software. In addition to developing software by itself, the main method is to establish alliances and cooperate with various CAM software. On the whole, it shows a dull sense of software, which also makes it look a little depressed in the field of measurement.

For many professional software, industry associations, research institutes and universities can often play a very important role. Japan AMTEC can be used in the field of gear transmission design and plastic / powder metallurgy gear design and analysis. It is a set of gear transmission design and analysis tool software developed by the subordinate organization of Japan gear Association. Windows LDP is the gear load distribution analysis software developed by the gear dynamics and gear noise laboratory developed by the Department of mechanical engineering of Russian State University. The domestic gear transmission CAD Integrated System Software zgcad is developed by Zhengzhou Institute of machinery, including common gear transmission design and calculation methods.

It can be seen that the development trend of foreign manufacturing industry, whether it is the machine tool of industrial mother machine, the measuring instrument related to precision and quality, or the cutting tool as the largest consumable in the factory, is moving closer to software. The combination of software and hardware is the king, which also makes foreign industrial equipment manufacturing more and more intelligent. Domestic manufacturing lacks such an environment. Hardware is not hard, software is softer. This form of confrontation on the battlefield is similar to green dragon sword and laser sword, which is the competition between the two times.


Those wonderful from the University  
 


There are many options for boiler drawing software, such as SolidWorks of Dassault or domestic software. This kind of software is generally general CAD software. However, in the boiler process software, it needs to have a deep industry background, because the complex simulation calculation is needed for the heat transfer, flow and medium inside the boiler. Many enterprises often use proprietary technology, such as early Hitachi, Ge, Siemens and ABB boilers, which have a large number of self-developed software. This is also one of the core technologies of the enterprise. At present, such software is basically commercialized, such as gt-pro thermoflow of MIT, ked software of Germany and gatecycle heat balance analysis software of Ge. In order to make up for the lack of programming ability, industrial giants will also choose to cooperate with external software companies. For example, gatecycle was jointly developed by GE and a software company.

In this regard, Zhejiang University has done a very good job. The boiler body simulation software Bess developed by Zhejiang University is basically adopted by the first 50 boiler plants in China. Like the track of MIT's success, the main creative team of this software first came from the school of chemical engineering of Zhejiang University. This sounds like a layman, but it's not, because the process of boiler combustion is essentially a chemical process. The success of Bess software makes people see a rare good case of the combination of industry, University and research. Since 1995, supported by the national basic project, there has been a boiler plant among them; The following ten years of grinding and the involvement of more boiler factories have contributed to the rise of this domestic boiler software.

This development track is common in the history of foreign software development. It follows many basic laws of software development, and the state funds support basic research, but the market application side has been hand in hand. After the project acceptance, continue to invest funds, add more applications, and finally move towards commercialization.

The team of Aspen, the top software for chemical process simulation, is from the Department of chemical engineering at MIT. Aspen Plus is a process simulation and optimization system for the process industry, which is widely used in the domestic chemical industry. This is also one of the important life points of China's domestic process industry. This software originated in the late 1970s. The oil crisis triggered a huge driving force to improve the efficiency of the whole process industry. A new process simulation software developed by MIT entrusted by the U.S. Department of energy. The name of this project is "advanced system for process engineering" (ASPEN), and the preparation of the whole software was completed at the end of 1981.

In the United States, according to the baidu act, the scientific and technological achievements produced by the basic research funds invested by the federal government can be transferred to universities. Universities, on the other hand, can endow the owners of achievements with great capital gains through authorization and patents. Therefore, MIT, which is best at commercialization, did not delay at all. It commercialized it the next year and established AspenTech. This software, called Aspen Plus, has launched more than ten versions and has become a world recognized standard large-scale process simulation software. A large number of chemical users, including countless chemical plants in China, are fertile soil for Aspenplus to test, sow and harvest. These valuable user experiences have also pushed Aspen's process simulation software to an unshakable dominant position. China's chemical, petrochemical and oil refining industries have naturally contributed to its rise.

Similarly, in the advanced process analysis APC software, Aspen's dmc3 also occupies a great advantage. The domestic central control software from Zhejiang University also has similar APC products, but the commercialization is relatively weak, which is mainly used in combination with the DCS system of central control. If Sinopec and other large enterprises can give more opportunities to Central Control APC, this take-off is just around the corner. As China's stock market is facing a large window period of software upgrading, APC's upgrading is in a rigid stage, and it is believed that central control will also usher in an outbreak period.

The biggest feature of these software is the industrial knowledge behind them, which is the essence of industry and the process secret that enterprises don't want to say. To describe these problems, we must solve them jointly with the help of mathematical equations, physical methods and chemical equations, and simplify the complex boundary conditions. It is this too mathematical requirement that makes it difficult for ordinary enterprises to turn their knowledge into software. This is not a problem that it enterprises can solve. It requires enterprises to have the ability of software engineering knowledge. University professors who can closely combine with practical applications often have better advantages.

Obviously, industrial software generally has strong professionalism. Many software originated from university or engineering consulting background. Without these basic or engineering backgrounds, such large-scale software cannot be developed. A simple it company is almost completely incompetent. For example, the American thermoflow software used for the thermal analysis of cogeneration in power plants is almost the same as Aspen. It is also from MIT and the Department of chemistry.

Throughout the history of industrial software development, universities and institutes are an important birthplace of kindling in order to cultivate industrial software in various industries. Activating the mechanism research advantages of universities and then combining them with engineering applications (domestic software academies have suffered great losses) is an important path to develop colorful industrial software.


Scientific computing three swordsman  
 


Scientific computing is the most common kind of software. Among them, in addition to the MATLAB of American MathWorks, which became more famous because of the interruption of supply to Harbin Institute of technology in June, there are maple in Canada and Mathematica in the United States.

Mathematica mainly does numerical symbolic operations. The engineering simulation and numerical value are much worse than MATLAB. This is a software established by mathematician wolfram, which is widely used in Universities for mathematical calculations. Later, the scientist also developed a search engine wolfram to answer questions directly, which is regarded as an important direction of intelligent search engine. But later, the interest of the Internet community shifted to the mobile Internet. Application apps bloomed everywhere. The search engine no longer became the only entrance to traffic, and the engine was not warm.

Similarly, maple is also a programming language for symbolic and digital computing environment. It is developed by Maplesoft in Canada to solve problems in mathematics related fields. It has built-in more than 6000 computing commands and more than 100 algorithm function packages. The multi system simulation mapsim software can add functions for multi domain physical modeling and code generation. This company has been acquired by Cybernet in Japan in 2009.

Scientific computing three swordsmen, or the combination of MATLAB and industry is the most extensive. After the event that MATLAB was banned in Harbin Institute of technology, domestic people were excited to find the topic of "domestic matlab", which also became hot rapidly. Suzhou Tongyuan software and Beijing Liangao software all have high voices. Realistically speaking, this is only a possibility, or it can be replaced in local functions. It is almost impossible to replace it all at once. Matlab is relatively complete in various simulation engines and numerical calculation tools, and is highly dependent on users. However, Suzhou Tongyuan software mworks also has certain advantages in some parts. It is based on Modelica physical modeling, which is a field that MATLAB started late but is catching up quickly.

However, the replacement of basic functions is not difficult. What is really difficult is the grasp of user habits and the construction of complex ecology. The algorithms and documents of application scenarios accumulated over time can not be polished day by day.

You can create a manipulator with a 3D printer in one day, but it takes months to figure out its circuit for all kinds of fine blood vessels. Due to the use of many users, its usability is very good, and its interactivity and graphical interface are unmatched. This is actually completely polished by users with their own hobbies. The Windows version of ABB's DCS operating system was first used in the Three Gorges project, and many bugs were built with the help of Chinese users. This once again shows that the software is used by users, and it is useless to rely solely on the efforts of suppliers. This is a fundamental reason why industrial software is difficult to develop rapidly. Today, Matlab is difficult to be replaced for a time. Over the years, it has been watered into the great wall of steel by the sweat and habits of users. Chinese universities and engineering circles are also one of the important irrigators.


Excellent users create excellent software  
 


Power industry is highly sensitive to security, and has high requirements for software simulation. In the decades of rapid development of electric power in China, power simulation software has also made great progress.

Power system software can be roughly divided into electromechanical, electromagnetic transient and real-time simulation.

Chinese electromechanical transient analysis software was introduced from the United States in the 1990s. After decades of operation and maintenance, it has undergone complete change and subversion, and completely rewritten the code. China Electric Power Research Institute has developed a comprehensive power system simulation program PSASP, which has completely independent property rights and is widely used in power grid companies.

The simulation software EMTP used for electromagnetic transient analysis of power system simulates high-voltage power network and power electronics. It includes the models for transformer phase transmission line, various motors, diodes, thyristors, switches, controllers and so on. It focuses on the operation of the system rather than the details of individual switches. The earliest EMTP program was led by the bonville Power Bureau BPA of the U.S. Department of energy at the end of the 1970s. Since this research and development belongs to public finance, its results can be provided to any interested group free of charge. By 1984, the pastoral scenery of free basic research and shared by the industry began to be broken. This program is divided into two schools. One school began to take the route of commercialization; Another school continues to defend the free route. PSCAD in Canada is well-known for this software. At present, the State Grid also has its own version of electromagnetic transient simulation in China, but the degree of commercialization is not as good as that in foreign countries.

With the development of power grid, relying solely on software simulation can not meet the requirements, so there are real-time digital simulation and digital analog hybrid simulation, the representative is RTDS. The biggest feature of this software is that it is very expensive. A set of RTDS software, with a simulation scale of more than 100 three-phase nodes, often 2 million yuan. China's power system can only be purchased continuously at the beginning. Later, I also began to develop ADPSS software. The performance can basically be compared with RTDs, and the price is only one third. The server used is also a domestic brand such as Inspur. Although some chips in the hardware of the real-time simulation system are imported, they have basically realized localization.

It can be compared with Canada, a power country. At present, the power system software developed in Canada has comprehensive solutions, including distribution network simulation software cyme, grounding simulation software CDEGS, electromagnetic transient simulation software PSCAD, large-scale power network simulation software DSA tools, etc.

From the perspective of power software localization, China's electromechanical transient simulation PSASP corresponds to DSA comprehensive software; Electromagnetic transient simulation EMTDC software corresponds to PSCA in Canada; ADPSS, which represents a higher level of real-time digital simulation system, is directly benchmarked with Canadian RTDS.

China's power system may be an industry that relies less on foreign software in various industries. This is not only related to China's largest power grid capacity in the world, but also related to the power system as the core energy industry, which has been pursuing an independent strategy. Due to its Electric Power Research Institute as the leader of basic research and a wide range of application scenarios, the development of software is relatively healthy.

China's nuclear power software is also not backward. Nuclear power software has nine specialties, including thermal hydraulics, reactor physics, combustion components and probabilistic risk, involving more than 200 programs. As early as 1984, after the establishment of China's Ministry of nuclear industry, its subordinate nuclear power center began to systematically transplant these imported software from workstations to different computers. This large-scale transplantation has left sufficient training opportunities for the development system of nuclear power software. At that time, the sources of nuclear power software were also diverse, some were purchased, some were presented by international friends, and some were brought back from abroad. For example, 77 programs such as ciataion core analysis and njoy multi group neutrons were purchased from the National Energy Software Center NESC of Aragon National Laboratory, as well as the Monte Carlo Morse general program presented by Oak Ridge National Laboratory. These are the assets of China's nuclear power industry when it started.

Starting from the core structure, nuclear power is divided into primary, secondary and tertiary equipment, while steam generators and pressure vessels need strict simulation. Considering that the general requirement is a random life of 60 years, no one dares to be careless in simulation verification. Previous checks were calculated manually according to ASME standards. A large safety factor has to be established. Now, the audit is in accordance with the standard specifications. You only need to look at the simulation report. Not only is fluid analysis and electromagnetic analysis very common, but even a screw and weld should be simulated. This is a field where the awareness of simulation goes deep into the hearts of the people, which also makes the development of nuclear power software have a deep foundation.

With the independent improvement of China's nuclear power, nuclear power software has also made great progress. In 2015, the public beta version of cosine software of SDIC was released, becoming a domestic software for nuclear power design and safety analysis, including 15 software in 8 categories, including thermal hydraulic design and safety analysis and core physical design. This breakthrough is thought-provoking because it follows the synchronous development of the country's third-generation nuclear power independent technology AP1000. At present, cosine software has completed the engineering application research based on AP1000 and Guohe No. 1 third generation nuclear power reactor, and its engineering application version has begun to emerge.

Petrochemical, nuclear power, power system and other large-scale equipment with high safety requirements, professional software has never been absent. These are often the focus of negotiations when importing foreign equipment and technology. In the introduction of a large number of foreign equipment, these programs with hard disks or floppy disks will not be ignored. Because many large industrial equipment (such as electricity, nuclear power, etc.) are naturally bound with software. For example, NETOMAC, the electromechanical and electromagnetic transient software of Siemens, was developed as early as the 1970s. Siemens later acquired PSS / E software of American company to further strengthen the analysis of transmission system. Software is a milk compatriot of equipment, which has never fallen. This phenomenon was actually only a weak signal at that time. However, some interested technical leaders have found this, and local amplification will promote the development of domestic software in this industry.

This also shows once again that the strength of industrial software in an industry actually comes from the confidence of users. If users trust a certain kind of software, it will be much easier for the software to grow and grow like bamboo shoots in the sun and rain. Ouyang Xiu's "oil man" has already revealed the secret of industrial software, "no other, but familiar". However, most domestic industries have never let domestic industrial software find the opportunity of "skilled technology" before. These mobile phone training sessions have been given to foreign software before. This forms a "system self-locking cycle". The more feedback users use, the easier foreign software is used, the more domestic software is ignored, and there are few opportunities to develop.


Clear scoring routine  
 


Professional industrial software is really difficult to count clearly, and tens of thousands of different software are completely possible. To find and understand these different software, one needs to start with the national economic industry classification code. Because behind every industry, there are traces of industrial software.

With the wider application of composites in industrialization, it is necessary to carry out structural design, analysis and size optimization around composites. Hypersizer is a professional software that includes hundreds of failure analysis methods. With its rapid analysis and composite material optimization ability, it plays a vital role in weight reduction in aerospace projects at home and abroad. For example, the high-altitude and high-speed reconnaissance aircraft sr71 of Loma, the wing of global eagle of Grumman, the engine nacelle of Airbus A350, etc. all use hypersizer software. The composite rear fuselage, central wing, flat tail and vertical tail of COMAC C919 are also inseparable from this software. It originated from NASA Langley Research Center, a well-known laboratory for aerodynamic research and wind tunnel. Swimming Prince Phillips's famous swimsuit shark skin was actually born here. It was a perfect experience of materials and simulation. This technology is now held by collier company in the United States. It can be combined with common commercial finite element software to automatically generate safety margin report for each component. This case is a typical example of NASA's basic research spreading outward into commercial software.

For an industry, it often adopts a comprehensive software system. For example, a shipyard will use plant design software such as French Schneider aveva (yes, designing a ship is designing a factory or a city). Then, CD adapco acquired by Siemens and star CCM, its general CFD software, will be used for polyhedron mesh generation and fluid analysis. This software has been dealing with turbulence, heat transfer and oxidative combustion since 1980. Despite the tools of these giant companies, the shipbuilding industry still leaves enough space for many small industrial software companies. NUMECA of Belgium can still create professional CFD software packages for ship and ocean engineering. This software includes hexahedral unstructured mesh generator hexpress and powerful post-processing tool cfview, and then coupled with the incompressible viscous flow solver isis-cfd developed by the French National Academy of Sciences, which can be used to simulate single fluid and multi fluid flows around ships.

The company was founded by the head of the Department of fluid mechanics at the Free University of Brussels. He wrote the aerodynamic numerical solver (euranus) for the European Space Agency (ESA) in the 1980s and 1990s. On this basis, the benefits of engineering software and commercialization follow. This shows us once again that there is such a smooth and close channel between universities and industry, national research funds and commercial software. Whether in the United States, France, Belgium and other European countries, the achievement transformation of national basic funds behind industrial software is not tardy. The transmission of intellectual property rights of industrial software from universities to commercial shelves is like a long pass on the football field, and then a shot. Together, one after another, one shot, completed all the scoring process. This is why foreign software is full of lively fish and shrimp everywhere.


Every track has a Chinese shadow  
 


An interesting thing is that there are always benchmarks for foreign software in China. The EPLAN electrical design software of Weitu company in Germany is widely used on electrical panels and cabinets, while the domestic electrical software corresponds to the EPLAN electrical design software; There are tolerance analysis software such as sigmetrix abroad, and Hebei Mingrui intelligence in China; Facing the three major foreign electromagnetic simulation software, the high-frequency electromagnetic simulation software of Eastwave incubated by Fudan University is also a brave challenge. As for the previously mentioned real-time machine integrating software and hardware of German dSPACE, Jingwei Hengrun in China is also doing the same work, rising rapidly with the help of the electronic control era of cars. COMSOL, a veteran star of multi physical field simulation in Sweden, as a platform, has actively developed app without code in recent years. It only takes a few hours to generate a simulation app. The young team of Tsinghua yundaozhizao is catching up, and even goes more thoroughly in the Internet.

Even in very small areas, such as Hunan lean transmission design software, it directly benchmarked the internationally famous gear software such as Swiss kisssoft, British romax, Masta, etc. Anhui Taize turbine aims at the CAE software concepts nrec of American turbomachinery. As the calculation software of energy conversion between machine and fluid, CN has always been the leader of rotating machinery. Cn design software is generally used in Aeroengine R & D in China. However, while authorizing the use, the United States requires a commitment that it cannot be used for military purposes. In recent years, American industrial software has been tightened again and again, which has also left development opportunities for domestic software. Taize turbine adopts the combination of software and engineering services, and adopts an integrated design platform to realize the integration of geometry import, storage and optimization. In China, it is favored by large industrial compressors such as Shenyang drum and Hangzhou oxygen. In the field of new energy, low-temperature waste heat and residual temperature power generation also brings new business opportunities.

This kind of "soldier to soldier", Will to will "The challenge scene is very common. German MAGMAsoft casting simulation software can simulate and analyze mold filling, solidification, cooling, heat treatment, stress and strain in the casting process. This is a classic software released as early as 1988. But it doesn't matter. Master level software has now met a young challenger, founded by doctors from Tsinghua University Beijing Shichuang company is here for this purpose, and adopts a more flexible SaaS subscription method.

Another point is more biased, such as the field of bulk materials. It sounds strange enough. In fact, it's around. For example, pharmaceutical agents and sediment excavated by loaders need particle mechanics simulation. This is the category of bulk material analysis. Its biggest feature is not only solid blocks, but also fluid characteristics. As a big country of construction machinery, Sany Heavy Industry and Liugong machinery are inseparable from this software. The fluid and solid coupling MpCCI software of SCAI Institute of Fraunhofer Research Institute in Germany has been cooperating with various commercial software since 1996 to realize the coupling analysis of different subject solvers. The software uninsim developed by Beijing Hegong company can realize this, and can also analyze the pollution characteristics of fuel / hydraulic oil.

This is a feature of the domestic industry. There are soul stirring challenges in every small gap. Such a challenge can only be described by "stubbornness". Because the size of the two is often out of proportion, but it does not prevent tenacious domestic players from focusing on their goals for years and decades. As long as you keep an eye on it, there will be results. Like German system modeling and simulation Modelon, domestic Suzhou Tongyuan keeps an eye on it and has achieved good results. In terms of plant management software and digital twin software PDMS, there is a good breakthrough for aveva of Schneider, France and yingtu of the United States, and the pipeline software of Zhongke Fulong in China. In the field of home design, many domestic markets, such as the early French software KD and the old Canadian 2020 design, have been occupied by Guangzhou Yuanfang software (owned by Shangpin homestead), kujiale and digital Dafang, which has also created a great trend of personalized customization of smart home.

Industrial software is like a road to the mountains. There are both roads and sheep intestines. It can be said that in every narrow mountain road, domestic software is like an indelible shadow, performing the great brilliance of small roles. Behind all this is the enterpriser's spirit of perseverance - determined to stay on the green hill and seek life after nine deaths. It can be said that industrial software or the battle of Shangganling, large or small, can be found in every small gap.


Notes: eating a small stove is better than cultivating soil  
 
 


It is frustrating to find out the whole picture of industrial software. It can be said that there are as many kinds of industrial software as there are industrial products. Industrial software is like industrial DNA. Each product has its own gene fragment. They are everywhere and look completely different, but they have strong commonalities at the bottom of the foundation. This means that it is not easy for a country to develop industrial software rapidly. Because it is not facing one or two software breakthroughs, but the loosening of the whole industrial foundation.

In this sense, simply looking for Star software and head software and enthusiastically giving birth to funds and policies are not in line with the development characteristics of industrial software. The first characteristic of the industrial software industry is that it is slow. The door-to-door daughter-in-law is as slow as a mother-in-law. There are no acute children and there are slow children. It is complementary to the degree of industrialization. Neither industry nor software. The second is wide. Industrial software is everywhere, just like the wild flowers in the field. It is very difficult to identify them one by one. Fertilize seedlings one by one, only occasionally.

This will naturally give people a deep impression, that is, what industrial software needs is full flowering, rather than artificially cultivating several landmark plants. This is a process of building an ecological jungle. Cultivating head plant stars is important, but building good soil and weather is more important. Supporting the development of industrial software, its complexity is far more than conventional imagination. Noisy enthusiasm and superficial investment can not solve the problem. China's industrial software policy must have the patience to face the "targeted poverty alleviation" with a hundred flowers in full bloom and seedlings everywhere. A company with dozens of people and an income of 10 or 20 million may be the best target for support. If we follow the way of large sum of money and large supporting funds, many excellent industrial software will be forgotten in the dark.

The most difficult part of developing industrial software is not the technical complexity, but that people are full of too many wrong perceptions of industrial software. (end)
