摘要: 采用各向异性平面非结构网格生成技术对曲面的参数平面进行三角剖分,从而得到曲面的非结构网格,作为三维非结构网格的边界网格.应用推进面法生成网格内点,增量法将生成的内点逐点插入现有网格进行网格细化,得到三维计算域的Delaunay非结构网格.讨论了非结构网格质量优化方法.给出几个算例说明方法的应用.

关键词: 非结构网格, Delaunay三角剖分, 数值网格生成

Abstract: An unstructured mesh generation method for three dimensional region is described. The boundary surfaces are triangulated by a two dimensional anisotropic triangulation method. Then the three dimensional meshes are generated by means of a constrained Delaunay algorithm with automatic field point creation. Methods for mesh quality optimization are also discussed. Several examples are given to show the applications of the method.

Key words: surface meshing, unstructured mesh, Delaunay triangulation, numerical mesh generation
