LES with a wall-function
Posted: Wed May 26, 2021 7:49 pm
Dear forum,
I'm running a LES.
I read from https://www.code-saturne.org/cms/sites/ ... e-Wall.pdf in the last paragraph that "This is the reason why Code_Saturne activates a wall-function by default for LES. If the mesh is fine enough, its influence vanishes and the LES becomes a direct numerical simulation."
Is there any way to check whether or not my LES simulation has activated the wall function by default? My mesh has a y+ lower than one, x+ and z+ low than 40 and 20, respectively.
Best regards,
Xiaoxue
