Remark: As FLUENT computes with the cell center, the value of y calculated is the same value as the center cell y-coordinate. Consequently, the height of the cell adjacent to the wall is twice the...

You have to use both values Y+ (for the mesh) and Roughness Height (for boundary condition). First, you choose Y+ = 1 or 30 for the cell adjacent...

This tool is for an estimation of Y+ because you need only an estimate to do a numerical computation. In the turbulence theory, the surfaces do not have roughness and that's why there is no roughness...
