摘要

铸造工艺的模拟仿真需要对铸件几何模型进行网格剖分，复杂铸件剖面采用合适的Delaunay三角剖分能极大简化运算。采用了生长式的点插入三角剖分方法，并证明了其严格符合Delaunay三角剖分准则。新的三角剖分方法对复杂铸件剖面剖分后得到的三角网格近似等边三角形，该算法已成功应用于华铸CAE软件中。

Abstract

The simulation of casting process requires mesh generation of casting geometric model. The appropriate Delaunay triangulation of complex casting section can greatly simplify the operation. The quasi-growth point insertion triangulation method was adopted

proving that it strictly conforms to the Delaunay triangulation criterion. The triangular mesh obtained by the new triangulation method is similar to equilateral triangle. The algorithm has been successfully applied to the InteCAST CAE.
