How to include....

Hi all,

Is it possible to specify "roughness coefficient" in the "Profiles"? If yes, How?

The "Turbulent Kinetic Energy" is 'coded' in the Profiles as "tke", likewise, What is the "code" name for the "roughness coefficient"?

Is it possible to incorporate the two effects i.e. the inlet velocity and the wall roughness coefficient through 'Profiles' for the same bounary at the same time?

You can't specify a profile for wall roughness. Also, roughness is only a property of the wall. Read up on how wall functions are modified through surface roughness.
