Mixed Element Type Unstructured Grid Generation for Viscous Flow Applications

摘要: A procedure is presented for efficient generation of high-quality unstructured grids suitable CFD simulation high Reynolds number viscous flow fields. Layers anisotropic elements are generated by advancing along prescribed normals from solid boundaries. The points such that either pentahedral or tetrahedral with an implied connectivity can be directly recovered. As they temporarily attached to a volume triangulation the boundary points. This allows local search algorithms used when checking merging layers, existing advancing-front/local-reconnection generate isotropic outside region. Results variety applications. results demonstrate efficiently and consistently complex configurations.
