| Abstract: | 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. |
