WebI'd suggest checking out the channel395 tutorial in tutorials\incompressible\pimpleFoam to see the usage of LES turbulence models. You'll also need the same boundary conditions for the solver (such as nuSgs, nuTilda, etc.) That should be about it, and if you're missing something the error should point you toward something else to copy/modify. cumberland county technical education center
