Improved grid quadrilateral mesh generation

An IGMG (Improved Grid Mesh Generation) is proposed in this paper. The algorithm combines the advantages of grid algorithm and traditional triangulation Delaunay algorithm, it generates quadrilateral/triangle mixed elements that ensured the overall and local performance. The result meshes meet the quality requirements of finite element mesh for automotive panel stamping forming simulation software. Practice has proved that the IGMG to be robust, efficient, generating meshes with high quality and easy to be implemented in practical applications. The algorithm has been successfully integrated into the commercialized stamping simulation software-KMAS.
