Generation and Optimization of 3D Unstructured Meshes
Jun Zhang · 2003
A new tetrahedral mesh generator based on Delaunay method is described in this paper. The generator can create good quality volume meshes fast. To ensure the existence of boundary sides and faces, local tetrahedralization method is adopted, needing add no node into the origin surface triangulations. Inserting new node in circum-centers of the existing tetrahedral. After inserting all interior nodes, some optimization algorithms including edge deletion, edge/face swapping and mesh smoothing are employed to improve the mesh quality. All Slivers can be deleted.
