Hexahedral mesh generation for geometry with hole-featured constraints
摘要
Abstract
For the difficulties between hole structure caused by the change of the boundary curvature, a hexahedral mesh method based on the mapping method was proposed.In this method,characteris-tics of sub-domains were first proj ected to the same surface,then multiple holes were encircled and va-rious subdomains were connected effectively.Path throughout the whole structure was searched by setting the direction of sub-domain boundary,then each sub-domain boundary interval was calculated based on the path.The final full-hexahedral mesh was generated via transfinite mapping method.Re-sults of examples show the effectiveness and robustness of proposed method to generate high-quality hexahedral mesh,which can solve the mesh compatibility problem of different hole characteristics.关键词
