Hello,

Can you please help me where to access the 'Wall Roughness' option as it is shown in the attached screen?

I know it is a strange request (since I've had a question in relation to that at: Wall Roughness, AIM ), but now I cannot find it in the Wall settings (where it makes sense to me), neither I can locate a 'route' to it in the Help.

Thank you in advance!

Hello steelxpert

Wall Roughness settings are available under Wall Boundary condition as seen below. However, this option only appears when you have selected k-ω turbulence models under Physics Option. Please check if you have enabled Turbulence Model and selected any of the k-ω turbulence models.

Hello Naresh Patre

Thank you for your answer.

RANS Model / Option was set to k-w SST, however I also engaged the 'Boundary layer transition model' that made it Wall Roughness option inactive.
