Subject: [Nektar-users] Implementing rough wall condition

Dear all,

I am relatively new to CFD and Nektar++. Although there are much studies perfomed by Nektar++ on flows over rough surface/bed, I could not find detailed information on how to define a rough surface.

I intended to define a rough surface/boundary (not a single roughness element or hump), and then, to investigate the boundary layer developed over this surface. For this purpose, do I need an external program like GMSH or is there any parameters (such as Nikuradse equivalent sand roughness or roughness height) or modules implemented in Nektar++? Any help would be greatly appreciated!

Many thanks,
