Structure Analysis With 3D Hexahedral Meshes Generated by a Label-Driven Subdivision

Liu Bo  Liu Xuewu  Ling Xiaoming  Zhang Xingui  Wang Zelun  Liu Wei  
【摘要】:For structure analysis with the finite element method(FEM),the hexahedral element is preferable to the tetrahedral one from the viewpoint of accuracy.Previously,we had introduced a label-driven subdivision method for a two-dimensional mesh and showed that the meshes generated by our method were useful for structural analyses.In this study,we extend our two-dimensional algorithm to three-dimensions and verify that the meshes generated by the proposed mesh-subdivision algorithm are useful for structural analyses.
