| Abstract: | Three modes for refining finite element meshes locally are proposed, in which me shes are refined near the key-point, in the circle area or in the rectangle are a. In the embedded regions that are constructed for refined meshes generation, a n algorithm based on Delaunay triangulation is then employed for the generation of graded meshes. In this algorithm, nodes and elements are generated dynamicall y and simultaneously, and the refined meshes generated in the embedded regions a re embedded into the original meshes. As a result, meshes are refined in the key areas. Examples show that the meshes refined by the proposed method are of good quality and can satisfy the requirements of finite element analysis. |
