In recent days, , At the Kunpeng developer summit 2022 Activities of , Chen Xi, academician of the Chinese Academy of Sciences, was invited to deliver 《 Innovation and development of independent industrial software 》 Keynote speech of ！

Chen Xi, academician of the Chinese Academy of Sciences

Academician Chen said , China's industrial software is a strategic place for China's scientific and technological breakthrough , It is the strongest driving force for the continuous innovation and upgrading of China's manufacturing industry , Industrial software must develop its own core technology , Especially industrial simulation software . The following is the full text of academician Chen's speech ：

Thank you very much for speaking at this summit . I have been doing fluid mechanics all my life , Do turbulence research , Turbulence research has no analytical solution , So I've done numerical solutions all my life . Be me high-performance computing, Various solutions and development methods ,turbulence modelling,molecular dynamics,  I have touched all methods involving fluid mechanics . My idea now is , Can we try our software on Kunpeng , In particular, I heard that Kunpeng has many useful libraries , Let these industrial software match 、 Embedded in the basic software and hardware platform independently developed by our country , So I have a learning attitude today , Let me share with you some of my recent research .

Industrial software is a service enterprise “ planning 、 Research 、 production 、 sales 、 service ” Whole process products , Enterprises almost above the waist , Industrial software is rarely used . There are four main parts of industrial software , R & D and design are CAD、CAE、PLM、PDM; The other is information management , image ERP; There are also production control classes and embedded , Now I am mainly concerned with R & D and design . I think , Research and design is the most promising application to Kunpeng , It is most promising to apply to shift-computing Of .

Industrial simulation software belongs to industrial software of R & D and design , In the process of product development , Use computer for modeling and performance simulation analysis . Industrial manufacturing process , The first step is 3D design modeling . For example, building airplanes , We must first give the shape of the plane digitize. Then make a physical model , Judge boundary condition , Such as incompressibility of fluid mechanics and so on , Another important step is to establish the grid , Establish mathematical model and numerical model . Then numerical solution , That is to solve partial differential equations , This is also the hardest part , All supercomputing is focused on numerical solution . When you get the results , Also do post-processing analysis , According to the physical equation 、 Law to explain , And feed back to industrial design . The above is the product development process based on industrial software .

The application value of industrial software simulation is amazing , For example, the manufacture of aircraft , It does computer simulation first , After doing a few experiments , So a lot of time is spent using computers to simulate the aerodynamic behavior of aircraft , Structural behavior , resistance , lift , Torque and so on . most important of all , Simulation software can replace experiments , I heard that the automobile industry makes sludge , The oil sludge needs to be made for several months , And the real calculation , About oneortwo days , And if we use artificial intelligence , We hope to shorten the time to a few hours .AI+CAE, This is the future development direction . Of course , Through numerical optimization and design , It can also increase efficiency and reduce materials 、 Improve the performance of the product 、 Technical level and market competitiveness .

Industrial software in today's Chinese market , The annual growth is 20% Up and down . Some people say , Industrial software is a zero sum game , I don't think so , I think China's industrial software can be compared with the United States 、 Western industrial software , Even better . But let's look at the top ten suppliers in the domestic industrial software market , stay CAE plate , There is no domestic self owned brand software , Very disappointing , So we are really trying to solve China “ thetime ” problem .

Industrial software is widely used in all walks of life , Let me give you a few examples , Like a plane 、 The engine 、 A ship 、 automobile , Automobile is the most widely used field of industrial software , And marine dual carbon technology , Including natural disasters 、 Treatment of pollution diffusion and other problems . Look at it this way , Industrial software plays a very important role in the whole national economy . This piece of , We still have a big gap with the world's top level .

For fluid mechanics , Why is turbulence so difficult ？ Because it requires a lot of calculation . The plane is flying , Near the intersection of the body and the air , Is the calculation accurate , Determines the resistance of the aircraft 、 lift . The calculation of this process is very, very large , So direct numerical simulation is difficult , So we developed something like RANS,HYBRID RANS/LES,Wall-resolved LES And so on . We are 2012 year , In the world, the variational method is first proposed to solve difficult problems , So the theory and calculation are very complicated . In principle , aerodynamics , The core problem of fluid mechanics is turbulence .

Let's take a look at China C919 And the simulation of car wading . From this point of view , Our country's industrial software and world-famous software Ansys、 Dassault 、 Siemens can compete , Fluid mechanics software , For example, our Guangdong “ Casting soul ” plan , In fact, they are doing these things . I think , Industrial software in China ,5 The year can be compared with the international ,10 In, you can compete with international top software . We welcome the developers of Kunpeng to cooperate with us , Put our software on Kunpeng's server , Try using its library .

We do more now , It's trying to combine industrial software with digital twins . Everybody knows , Now the country advocates digital economy , The first document of many provinces this year is about digital economy , Talking about digital twins . The number twin has three big pieces , Digital acquisition , Algorithm , Software . The first generation of digital twins , After collecting the data, input it into the screen and display it , This twin of numbers lacks the ability to predict . And the real smart city , Digital twins are useful , It combines the digital economy with the predictability of industrial software , This requires AI+CAE. It works AI I'll use it AI, We found out recently , Some simple hydrodynamic problems , utilize AI Solution can save 10 Of 3 Computing space at power level . So I think the next version of digital economy should be AI and CAE The combination of . For example , When the Fukushima tsunami comes , Under the premise of facing the threat of nuclear radiation , How should the whole city plan the evacuation plan ？ At this time , We can learn deeply and CAE The evacuation plan is immediately obtained through the simulation of . In order to solve such an emergency public security incident , Digital twin cities need predictability , Therefore we need AI+CAE.

About the application of simulation cloud platform , I want to say two things , First, the importance of supercomputing , It provides a very powerful data storage Ability ; The second is cloud platform , Cloud platform is to transform industrial software from ToB to turn to ToC Key . image CAE Such industrial software is mainly ToB, I think with the development of cloud platform , Yes, you can join ToC Of . We have also made many attempts in this regard , Such as wind resource assessment . Establishment of wind farm , The whole terrain , The whole measurement data assimilation . This is what we really say AI、 Assimilate data and GIS add CAE To make predictions , Sense of opportunity , Arrange the wind farm , Including the offshore wind energy project we plan to carry out now , This may be the core of truly solving ecological problems .

Finally, I want to emphasize this idea , Is the digital economy of our country , Should be AI+ Number twin +CAE. I think this is industrial software outside the traditional industrial manufacturing field , A very important new sector —— With the digital economy 、 Data acquisition and control AI Coordinated development under the same system . There is a long way to develop independent industrial simulation software , We need the market , Need talent . Guangdong is very good , Opening up the industrial software market , Many enterprises have also participated . Before, there was no Western monopoly on our technology , Our own industrial software is difficult to develop , So I think the time, place and people are right for the development of independent brand industrial software .

How about myself , stay 2020 After leaving the post of president of South University of science and technology in , Came out to integrate and establish a company called Shifeng Technology . When I used to be a professor , Unfortunately, industrial software has not been given enough attention , And when I really came out , When you care about applications , It was found that industrial software is closest to our social production and operation , The closest , above all . So in the past year and a half , Our enterprise has developed 200-300 people , Make all kinds of industrial software , Now it's coming out 13 A relatively mature industrial software , Fluid , Of structural materials , Electromagnetic field , Heat and mass transfer , optics 、 Acoustic . We have set up our subsidiaries in major industrial core cities , We also talk with Peking University and Tsinghua University 、 West University of Technology 、 Jiaotong University, etc . Our idea is to put the good things in technology research into software applications . So we are with many professors of South University of science and Technology AI A lot of work has been carried out in combination .

I especially like a slogan of Huawei ：Bring digital to every person, home and organization for a fully connected, intelligent world.  My ideal is to one day “digital” Replace with “ Industrial software ”, Thank you !
