1 boundary layer vs 3 layers HEX mesh Test at strict yPlus20-175

About this project

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.
