Parallel AFT Tetrahedral Mesh Generation for JAUMIN
摘要
Abstract
Unstructured mesh application software programming framework JAUMIN (J adaptive unstructured mesh applications infrastructure) supports rapid development of multiple petascale parallel application softwares, and has been successfully applied to structural mechanics analysis and optimization design of major scientific de-vice,fission energy and other areas.In these applications,the mesh generation is a key step,in order to accurately depict the physical phenomena corresponding to the complex geometry,the fast generation of high quality and high precision mesh is required.This paper introduces tetrahedral mesh generation method by AFT(advancing front tech-nique)which seamlessly integrates into JAUMIN and provides parallel tetrahedral mesh generation for those appli-cation softwares based on JAUMIN,its main features are:(1)A coarse volume mesh is generated first to provide the basis of partitions,then in sub-domains,AFT method is used to ensure the consistency of interfaces.(2)The body fitted surface mesh refinement is used to make the grid more and more close to the real geometry.(3)Interfaces mesh opti-mization step further improves the quality of grid.The proposed method can generate hundreds of millions of tetra-hedral meshes quickly for practical engineering applications,and has good expansibility.关键词
