Automatic generation of unstructured grids with Delaunay triangulation and its application

摘要

This paper is consisted of two parts. In the first part, a method is described which generates two-dimen- sional triangle mesh using the Delaunary triangulation criterion. An automatic algorithm was proposed which combine several advantages of the existing methods. Local mesh refinement can also be easily performed with This method. Examples of generated grids were presented For several convex, non-convex and multi-connected do- Mains to demonstrate the effectiveness and feasibility of The proposed method.
