Abstract

A method of generation boundary layer mesh has been presented. This paper describes the generation of semi-unstructured prismatic/tetrahedral meshes for three-dimensional geometries with thin thickness. By of fretting of surface triangle elements prismatic/tetrahedral meshes are generated and using the node relocation method of this research intersected meshes can be efficiently improved. Finally tetrahedral meshes are automatically generated at the rest of the domain. Sample meshes are constructed to demonstrate the mesh generating capability of the proposed algorithm.
