| Abstract: |
| High Reynolds number viscous flow simulation has special requirements on the orthogonality of mesh in boundary layer.For complex geometries, it is very difficult to generate a boundary layer mesh automatically.In this paper, a double-front advancing method is proposed, and an automatic boundary layer mesh generation algorithm for complex geometric shapes is developed.In order to improve the quality of the generated meshes, local geometric features are treated with various techniques.Double-front advancing method is applicable to the generation of boundary layer meshes of multi-block structural meshes and hybrid meshes.The validity of the algorithm is verified by several model examples. |
