Hi everybody.

Since a couple of days i'm looking for the propers boundary conditions that i have to use in an incompressible LES case (pisoFoam).

I'm simulating the turbulent flow inside a wind tunnel.

My $y^+$ is about 35, exept for some small zones where snappyHexMesh refined the mesh around the turbulence generators. (is this ok?)

I'm looking for:
  • a smooth wall function
  • a rough wall function
  • a free slip condition

I know that it's a complex topic and it's a long answer what i'm asking for, but could you at least point me where can I find this kind of information?

Thank you very much,
Luca
