Hi OFoamers,
I would like to ask you: how muSgsUSpaldingWallFunction work?
what's the meaning of "value uniform"?

for example, in firefoam/les/oppositeBurningPanels/0/mu I find:
type muSgsUSpaldingWallFunction;
value uniform 0;

Is there any way to consider roughness in this wall function(like ks for mutRoughWallFunction)?
There's any wall model that consider wall roughness in les turbulence?

Dear gimba
it is related to using a constant for all or a distribution.
if you want you can develop your wall function. but it does not have any wall function for roughness
