Wall roughness

Hello everyone, I am a beginner with SimScale and I would like to know how to add wall roughness into a simulation. I saw it is possible but I cannot find how to make it. Someone could help me? Thanks a lot!

Hi @bertrand,

Welcome to the SimScale forum! You’ll find how to add wall roughness in the following post (be sure to click on the image to see the full screenshot):

Don’t hesitate to continue this thread if have further questions.

Happy simulating!
