True 3D graphics processing and virtual reality

With the development of high-performance DSP chips dedicated to graphics and multimedia information processing, the graphics processing capabilities of PCs will increase hundreds of times in the past two years. Coupled with the development of 3D graphics algorithms, graphics computing and parametric modeling algorithms, fast true 3D virtual reality technology will mature. Therefore, the pre- and post-processing systems of CAE software will have new developments in complex 3D solid modeling and related static and dynamic graphics processing technologies, such as complex 3D solid modeling and corresponding adaptive finite element segmentation, complex dynamic physical field virtual reality and instant prompts, etc.

Object-oriented engineering database and its management system

High-performance, price-performance, large-capacity storage and its high-speed access technology are developing rapidly. The hard disk capacity of PCs will soon reach the TB level from the GB level. Users will require that more calculation models, design plans, standards and specifications, and knowledge information be included in the CAE software database, which will inevitably promote the development of CAE software database and its data management technology. High-performance object-oriented engineering database and management system will appear in the new generation of CAE software.

The current CAE software for multi-phase and multi-state medium coupling, multi-physics field coupling and multi-scale coupling analysis is limited to engineering and product analysis of macroscopic physical and mechanical models. Although a few softwares are involved in micro-electromechanical system analysis, their physical and mechanical models still have certain problems. It is worth pointing out that the strong coupling problems of multi-physics fields, multi-phase and multi-state medium coupling problems, and especially the coupling problems of multi-scale models are still in the basic frontier research stage. However, they have become the key research topics of scientists at home and abroad. Due to their strong industrial background, any breakthroughs in basic research will be quickly incorporated into CAE software. In the near future, a new generation of CAE systems will be formed, ranging from the prediction and simulation of material properties to the prediction and simulation of component and entire product performance, integrating computer-aided material design and preparation, to engineering or product design, simulation and optimization.

High-performance CAE solution technology CAD/CAE/CAM adapted to super parallel computers and clusters has become a powerful tool for technicians to implement technological innovation. Hundreds of billions, trillions, petaflops and quantum computers are about to be born, and distributed parallel computer clusters are about to be put into use. To adapt to this situation, new high-precision and high-efficiency parallel algorithms are being studied, and some practical new algorithms will continue to come out. These new high-performance algorithms will inevitably be made into CAE software modules, so that when simulating complex engineering or products, they can give full play to the software and hardware resources of super parallel computing systems and obtain calculation results with high efficiency and high precision.
