To determine how much difference in results values will be seen if 1 boundary layer is used instead of the more accepted practice of 3 layers for a CFD HEX mesh (with unattached flow) within a very strict yPlus wall function range of 20-175 using the kW_SST turbulence model.  The meshes have about 99 percent of the geometry surface area within yPlus20-175. | Simulation project by DaleKramer
