This paper presents a robust and automated approach to generate unstructured hybrid grids comprised of prismatic and tetrahedral elements for viscous flow computations. The hybrid mesh generation starts from a triangulated surface mesh. The prismatic elements are extruded based on the weak solutions of the Eikonal equation to generate anisotropic elements at boundaries, and finally the isotropic tetrahedral grids are generated to fill the rest of the domain. The presented hybrid meshing algorithm was validated using a ball valve model under both steady and unsteady conditions. © 2006 Springer.
