二维有限元网格全自动生成方法

摘要

The main area of this paper is to research the 2D triangle mesh generation of arbitrary domain, in which a new approach is used to generate the inner grid-nodes of meshes. Then the triangle shape factor is introduced to gain regular triangle mesh. The results show that the method is reliable, and the meshes have good shape.%主要研究二维有限元网格全自动生成方法。提出一种新的节点生成方法，通过实例验证该方法可靠。采用三角形形状因子评定三角形网格质量，可减少三角化的时间，优化三角网格质量。
