Stratified wall shear on a circular cylinder

      Dear all,


      Does anyone know the reason of the stratified wall shear stress on a circular cylinder as shown in the picture? The wall shear stress should be continuous on the cylinder surface. I used turbulence model of k-w SST and created mesh from ICEM in ANSYS. Thanks!


      Best regards


      Allen

      Might be related to mesh-to-surface projection in ICEM:
      already test what happens when either Settings>Meshing Options>Hexa Meshing>Project to bisplines is enabled or a tighter (e.g. 1e-5/1e-6) value for Settings>Model>Triangulation Tolerance has been set?
