msahin.ae00 is on a distinguished road
When SU2 gives the y+ values on surface data file, how y value is computed in the following equation:
y+ = u_* y/\nu
When l use anisotropic elements next to solid wall, l see that Cf_x value looks normal. When l go to y+, it is completely irregular. In SU2-6.2.0, the distance function is modified to the distance to surface, rather than surface grid nodes. I think currently y value is not using normal distance to surface, but the edge length. Can any one verify that?
