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
