Now both the nutkRoughWallFunction and nutURoughWallFunction us the same field based Ks and Cs input to support non-uniform surface roughness. Note that nutURoughWallFunction is not exactly consistent with the nutUWallFunction in the limit of roughness height = 0 and also not consistent with nutkRoughWallFunction, particularly if the near-wall cell is in the laminar sub-layer for which nutURoughWallFunction is currently incorrect. Significant further work on the nutURoughWallFunction is needed to make it consistent with both the nutUWallFunction and nutkRoughWallFunction BCs.

About OpenFOAM
OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
