Hi foamers, do you know if and when, using komegaSST, is required nuTilda and epsilon?
Best regards to all!

nuTilda is the turbulent viscosity-like variable in the transport equation for Spalart-Allmaras based models. It is not required for kw SST.

Epsilon is the turbulent dissipation, which is important for k-epsilon based models.

The only variables concerning the SST model are k and omega.
