| 摘 要： | 在产品虚拟样机多物理场的性能分析和仿真过程中,由于分析目的和分析工具各不相同,各种物理场的有限元网格模型和仿真结果数据都是异构的。如何将异构有限元网格模型的几何和物理信息进行耦合,集成到虚拟环境中进行网格图形显示与结果数据可视化仿真是亟待解决的问题。提出产品多物理场异构有限元网格的几何特征映射与仿真结果插值方法,分别提取各异构网格模型的拓扑信息,建立过渡网格模型,根据空间相对位置将各异构网格节点与过渡网格模型节点进行耦合映射,实现异构网格模型物理属性到几何特征的映射。开发基于异构网格耦合的机械产品虚拟样机多物理场可视化仿真系统。

| Abstract: | In the process of simulation of multiple physical fields in virtual prototyping of mechanical products,the finite element meshes and simulation results are heterogeneous due to the difference of purposes and tools of analysis.It is important to realize the integration and visualization of finite element data of multiple physical fields by coupling the geometrical and physical information of heterogeneous models.A novel method of coupling of heterogeneous finite element meshes and interpolation of simulation... |
