Hi, I am using the interFOAM solver for turbulent flows in pipes. I want to investigate the effect of wall roughness on velocity profiles. How to introduce wall roughness in OpenFOAM? is it through a BC or changing the material of the wall. I have done the meshing in fluent and converted.

Thanks .

Tobermory will become famous soon enough
As in any CFD code, wall roughness is a boundary condition effect - try google it and you will quickly find nutkRoughWallFunction.
