摘要
利用人机结合的方式,对由CAD环境下绘制的矢量型二维网格图形进行结点、边线的整理,并根据它们的拓扑关系进行单元的识别,最后生成可供有限元分析使用的数据信息.此方法可完全按人的意图生成网格且对计算机软、硬件的要求甚低.
An interactive approach to generate two-dimension finite element mesh is presented in this paper.Nodes and links,two kinds of primitives can be achieved from the mesh graphics information created by the CAD softwares.Then,based on the topological property of the two kinds of primitives,the elements are recognized.At last, the data information which is used in the finite element analysis are generated.By the method, the mesh can be completed in accordance with personal opinion.
