The boundary condition is derived from inletOutlet condition. Therefore, in the event of reverse flow, a zero-gradient condition is applied. The order of precedence to input the empirical model constant Cmu is: turbulence model, boundary condition dictionary, and default value=0.09.; The empirical model constant Cmu is not a spatiotemporal variant field. 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. howler battletech
