Hi all,
I am working on a simple geometry : a pipe of a 33.7mm diameter and 2m long. My mesh is hexaedric with refinement at the wall. This is the link to it :

The simulation is a simple Poiseuille flow with a velocity inlet (Reynolds number=60000), an outflow and the rest is a rough wall. Which advanced option should I use in Code Saturne in the turbulence model panel (I simulate with a k-epsilon model), a one scale, two scale or scalable wall function? I am not quite sure of my results near the wall, especially when the roughness is high (between 0.1mm and 1mm) and until now I worked with a two scale option and it seems to me that when you refine your mesh the scalable wall function is more suitable.
Thanks for your answer,
Best regards
