The research on the improvement of triangular mesh generation

摘要

The problem which is solved firstly for numerical solution of partial differential equations is the mesh generation to computational domain. To improve the efficiency of mesh generation and ensure the grid quality, this paper adopts the grid generation which combines the advantages of Delaunay with advancing front technique, and utilizes advancing front technique to generate initial mesh in the border. It also utilizes the way of Delaunay to generate generation node in the interior of initial mesh, which makes global grid in the end.
