Tetrahedralization of Hexahedral Mesh
摘要
Two important classes of three-dimensional elements in computational meshes are hexahedra and tetrahedra. While several efficient methods exist that convert a hexahedral element to tetrahedral elements, the existing algorithms for tetrahedralization of a hexahedral complex limit pre-selection of face divisions. We generalize a procedure for tetrahedralizing triangular prisms to tetrahedralizing cubes, and combine it with certain other triangulation techniques to design an algorithm that can triangulate any hexahedra.
