摘要 在引入非Delaunay三角形,非Delaunay边概念基础上,将Delaunay三角化方法和前沿生成方法有机结合起来,对于任意单连通或多连通平面区域,提出了一个有效的内部区域节点生成方案,它不仅保证了局部和整体网格的质量,而且计算效率大大提高。本文工作已作为前处理机在注塑模CAE软件Z-Mold中实现。 With the introduction of “non-Delaunay” triangle and “non-Delaunay” segment, this paper integrates the most popular mesh generation technique,namely the Delaunay triangulation algorithm and the method of advancing front. An efficient scheme for generating interior nodes over any planar domains is presented, which ensures good quality mesh. The present work has been implemented in the form of a pre-processor in the injection mold CAE package Z-Mold.
