Hi!

These are the results obtained for the ZPG flat plate with distributed roughness.
The simulations compare the Wilcox (2006), Knopp, and Aupoix rough-wall boundary conditions within the SST turbulence model, as implemented in su2code/SU2#2573. The results are consistent with those reported in the literature.

Below, I present the results in terms of the log-law profiles and velocity shift for the different boundary conditions, using the uploaded mesh file: mesh_flatplate_turb_273x193.su2.

Finally, a comparison between the boundary conditions is provided for kₛ = 400 µm, corresponding to the fully rough regime.
