任意多边形域内四边形有限元网格全自动生成方法

AN APPROACH TO AUTOMATED QUADRILATERAL MESH GENERATION IN ARBITRARY POLYGONAL REGIONS

本文提出了一种任意多边形域的四边形有限元网格全自动生成方法。该方法可以生成全部四边形，网格质量较好，速度也比较快。文中介绍了它的基本思想和算法实现，并给出了实例。该方法已用于汽车覆盖件零件等复杂几何形状的有限元网格划分。

In this paper,an approach to automatical mesh generation,which meshes arbitrary polygonal regions with all-quadrilateral,good quality elements in high speed,is presented,The basic theory is described,the performance of arithmetic is evaluated,and some examples are presented.This approach has been applied to finite element mesh generation of complicated parts,for example,automobile panel with plastic forming.
