Dear all,

I would like to compute Delta Y+ (first cell height scaled by intern zone scales) to know which boundary condition to set to k (zero gradient or uniform 0.0) and check the correctness of the cells sizes.

I am using a compressible LES solver (fireFoam), so I tried the yPlusLES utility but it needs nuSgs, so seems to be adapted for incompressible cases. Bt FioreFoam only computes muSgs and not nuSgs. How can I solve that problem ? Do I need to modify yPlusLES and divide muSgs by rho or is there an existing solution ?

Thanks

Francois
