Abstract
Meshing and remeshing are often needed to complete a metal forming simulation with a finite element method programme. In order to automate the simulation process and improve the simulation accuracy, an automatic mesh generator, AUTOMESH‐2D/3D, is developed in this paper. The generator can adaptively produce quadrilateral, tetrahedral and hexahedral element meshes based on geometry curvature, thickness, interpolation errors, etc. An improved looping method is used for two‐dimensional quadrilateral and three‐dimensional triangle mesh generation. The tetrahedral and hexahedral element meshes are generated based on the advancing front method and improved grid based method respectively. The mesh generation processes and key technologies are presented in this paper. Many examples of mesh generation with AUTOMESH‐2D/3D are given to demonstrate the robustness of the mesh generator.
