fedvasu is on a distinguished road
Hi Foamers,

I successfully ran a RANS simulation of industrial fan with all wall BCs,
pimpleDyMFoam solver and spallart-almaras RAS model.

I got results upto some time, I would like to continue that simulation with LES instead of RAS, what are the options how I need to refine the mesh. (one parameter is way off the experimental value)

For instance if I am using one equation eddy model, how to accommodate nuSgs for the solution with RAS?

quick help would be appreciated
