Resolving Boundary Layers with Unstructured Quad and Hex Meshing: On-Demand Webinar - Another Fine Mesh
Summary
All things being equal, CFD practitioners prefer to use hexahedral mesh cells in the boundary layer for the improved robustness and accuracy they bring to the flow solver. Starting with a geometry model of an aircraft, you’ll see the entire meshing process beginning with the generation of a quad-dominant surface mesh that is clustered to regions of high surface curvature. Farfield boundaries are generated using automated shape creation utilities. The same shape creation utilities are then used to define a source that provides off-body volumetric grid refinement to help track flow features of interest. The volume mesh is generated using T-Rex, our unstructured viscous meshing algorithm, which extrudes stacks of hexahedra and prisms that smoothly transition to an isotropic tetrahedral farfield.
