摘要: 在现有曲面非结构网格生成法的基础上,提出了一种新的曲面网格生成法——多点择优推进阵面法.它可在曲面上直接进行三角形网格划分,克服了映射法的网格变形问题,并且可以在网格生成结束后,对曲面网格直接进行Laplace格点松弛光顺.该方法使用简单,不受曲面块类型的限制,且网格质量高,可以为三维非结构网格生成提供高质量的初始阵面,并给出了若干个算例.

Abstract: A new algorithm to generate unstructured 3D surface grid is suggested,which can be generated directly on an arbitrary curved surface.The phenomenon similar to the triangular grid distortion produced by the mapping method is disappeared.The quality of the surface grid can be further improved by using Laplacian smoothing method easily.The algorithm can be used to provide highly qualified initial front for 3D unstructured grid generation.Several examples are presented.

Key words: unstructured grid, surface grid, advancing front method, grid generation
