Boundary Layer Meshing for Viscous Flows in Complex Domains.

摘要: High reynolds number ow simulations exhibit strong gradients normal to walls and across shear layers requiring much ner resolution of the solution in some directions compared others. To keep mesh sizes manageable for such problems, meshes with highly anisotropic elements are necessary. In this paper, a method generating boundary layer arbitrarily complex non-manifold geometric domains is discussed. A popular strategy generation generalized deal nonmanifold model topology as well generate better shaped elements. Results on con gurations presented demonstrate capabilities generator.
