Tetrahedral mesh generation in polyhedral regions based on convex polyhedron decompositions
作者： Barry Joe
关键词:
摘要: The input to the method consists of boundary faces polyhedral region and possibly internal hole interfaces, plus desired number tetrahedra other scalar parameters. is decomposed into convex polyhedra in two stages so that one length scale can be generated each subregion. A mesh distribution function, which either automatically constructed from first-stage polyhedron decomposition or supplied by user, used determine tetrahedron sizes subregions. Then a constrained triangulation polyhedron, with local transformations being improve quality tetahedra
