thanks for your reply. there still are some questions. for example, when I use SBES model based on the k-omega SST, how to calculate the subgrid viscosity? does the effective viscosity in fluent(Turbulence variable) include the subgrid viscosity? and under the SBES model, does S(strain rate tensor) represent the instantaneous velocity?
