If z-direction is the spanwise resolution, the cell size depends on the flow conditions. If the flow is homogeneous then the cell size dz+ can be O(20-30). But if the flow is confined in spanwise direction then you have to consider if it necessary the full boundary layer resolution and a non-homogeneous grid size.

Is there anybody willing to share a good mesh, which has been used for such an LES calculation?
