December 18, 2013, 08:39	switching from RAS to LES	#1
fedvasu Member Join Date: Oct 2013 Posts: 92 Rep Power: 12	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
