RANS models include; Spalart-Allmaras, a range of K-Epsilon models, both standard and SST variants of the K-Omega model as well as two Reynolds stress models. Where laminar-turbulent transition occurs, STAR-CCM+ has the option to use the Gamma-Re-Theta model to model its onset.
When more accurate capture of turbulent flow structures is required such as in the study of aeroacoustics, STAR-CCM+ has a number of options for both LES and DES modeling. For LES, the Smagorinsky, dynamic Smagorinsky and WALE subgrid models are available. For DES, the latest delayed and improved delayed detached eddy simulation models are available for both Spalart-Allmaras and K-Omega SST variants. Finally, the synthetic eddy method for the specification of realistic inflow boundary conditions is available for both LES and DES.
