Hexahedron Mesh Generation Method Based on Sub-domain Decomposition
摘要
Abstract
A new hexahedron mesh generation method was proposed herein.First,the feature edges of the domain were extracted and the appropriate decomposition face was generated according to the feature edges.Then,the complex geometry was decomposed into multiple sub-domains by the decomposition face and the structured hexahedron meshes were generated by the method of transfinite mapping in the sub-domains.Finally,the mesh of target domain was obtained by combining the meshes of all sub-domains.The method was capable of preserving transfinite mapping's advantages of the briefness in algorithm,high efficiency and high quality of the meshes,at the same time,could overcome transfinite mapping's shortcomings of bad geometric adaptability,which might only used to regular geometric shapes.Numerical experiments were presented to demonstrate that the new method may generate high-quality hexahedron meshes for complex geometries automatically which may not generate hexahedron meshes by commercial softwares directly.关键词
