| As to the increasing requirements for computational scale and expanding application areas of finite element method,an open general visual system is designed and implemented.The visual system is developed for large scale finite element computation visualization with over millions of or tens of millions of nodes.In the architecture design, the stream architecture is introduced.This architecture has the characteristics of high efficiency for both computation and communication,which meets the needs of large scale data processing.In the software implementation,factory method pattern and plug-in technology are employed which improve the expansibility and flexibility of the system.Several modules,like finite element model module,filter module and render module,are designed and implemented.In the large scale data visualization,using VBO and partial load,the large scale model can be displayed in real time.Several model examples are presented to show the feasibility and superiority of the system. |
