Is there a way of counting the number of nodes in the boundary layer in CFD-Post?
The first photo shows the velocity contour at 90% span and the mesh around the blade. Does it have the minimum requirement of 10 nodes in the boundary layer? The second photo shows the distribution of y+ around the blade. I specifed Y+=1 in turbogrid but the the distribution shows that the maximum local y plus is 5. Do I have to refine the mesh near the boundary? Is it correct way of inspecting Y+? I am using SST turbulence model. |
