Friction/Roughness factor for walls

[mdariz11]

Hello,
Is there any option to include friction or roughness factor in fds for wall.

Thanks in advance

LMGTFY -- How do I apply roughness in FDS Fire Dynamics Simulator?"

or, given that you have spelled "roughness" correctly, why not just search the FDS User's Guide?
