Development trend of CAE simulation analysis software

although CAE The function of simulation analysis software has been quite powerful , But it doesn't cover every field . The future development should have the following functions .

Coupling analysis of deformation system and multi lift system

The satellite antenna is analyzed 、 robot 、 Deformation and vibration of deformable systems such as landing gear under the simultaneous action of shape change and load ; Vehicle and track 、 Static analysis of multi-body coupling state such as vehicle and bridge 、 dynamic 、 Vibration analysis .

Multiphase loop coupling and multiphysical field coupling analysis

Multiple physical fields （ Force field 、 Seepage field 、 Temperature field 、 Electromagnetic field, etc ） Nonlinear coupling analysis ; Polyphase and polymorph （ Fluid 、 solid ）. Gas loop coupling analysis .

Multiscale coupling analysis

From the composition and structure of basic materials to composite materials , From qualified materials to components , And then from components to engineering / product , There are microscopic and microscopic models ; contrary , The infinite superposition of micro model and micro model is difficult to produce macro model . therefore , In the engineering / In the fine analysis of products , Objectively, we will encounter the coupling problem of multi-scale models . at present ,CAE The software is limited to the engineering of macroscopic physical and mechanical model / Product analysis .

From material design to engineering / The product design ,CAE The system integrates simulation and optimization . With the development of Computational Materials Science , In the near future , Computer aided material design will be integrated into CAE In software , Realize the prediction and Simulation of material properties , And the design of parts and the whole product 、 Performance prediction and system simulation , A set of computer-aided material design and preparation 、 Engineering or product design 、 Simulation 、 A new generation of optimization CAE System .

MEMS Catastrophe combination theory and submicroscopic analysis of polycrystalline media

With multiple physical fields 、 Polyphase 、 Multi state medium coupling theory and submicron 、 The development of nanoscience , Developed for MEMS Design calculation CAE Simulation analysis software is imminent .

For the strong confluence problem of multiple physical fields , Polyphase 、 The confluence problem of multi-state media , Especially the multi-scale confluence problem , At present, there is no mature and reliable theory , Still at the forefront of basic research . They have become the main research objects of scientists at home and abroad . Because of its strong industrial background , Any breakthrough in basic research will be quickly integrated into CAE Software , To support emerging projects / Technological innovation of products .

Software technology

In recent years , With DSP Chip development , The ability of computer graphics processing has been improved hundreds of times . With the 3D graphics algorithm 、 The development of graphic manipulation and parametric modeling technology , Fast 3D virtual reality technology has matured . therefore ,CAE The 3D solid modeling of software and the virtual reality technology of complex static and dynamic physical fields will be greatly developed .

Besides , High cost performance mass memory and its high-speed access technology are also developing rapidly ,PC The hard disk capacity of the machine will soon increase from GB achieve TB level . Users need to add more computing models 、 design scheme 、 Standard and knowledge information input CAE Software database . in addition , The database management system in the Internet and grid computing environment can manage multiple user storage at the same time / Large amount of unstructured and various types of data retrieved , And time / Space related , It should also have the advantages of relational databases , Object oriented database and its management technology , Support the definition of abstract data model , Support distributed computing in virtual computing environment 、 isomerism 、 Distributed data management , Support Internet And multi-user concurrency in grid computing environment /10 state 、 Advanced storage and query language , Protection of access rights and data ownership 、 Testing the spatio-temporal consistency and effectiveness of heterogeneous databases 、 Data consistency recovery under abnormal system state, etc .

With the rapid development of multimedia user interface and computer graphics technology , The narrow sense of voice input and output has become a reality . Computers have been able to analyze postures within a certain range 、 Eyes and gestures . The data mining technology of implicit information request also came into being . Can listen 、 see 、 say 、 Write 、 The computer of learning is coming out , These multimedia technologies will make the future CAE The user interface of the software is more intuitive 、 direct 、 intuitive , It brings great convenience to users .

With a single CAE Software functions are becoming more and more powerful , The number of modules is also increasing , It is composed of hundreds or even thousands of algorithm modules . A large number of design schemes are stored in the database 、 Standard parts 、 Industry standard 、 Norms and knowledge rules , To determine whether the design calculation results are correct . such , Users are faced with the problem of how to operate . therefore , In the future CAE Software will need a more intelligent user interface .
