Nonlinear eddy viscosity models
 

Hi all,

is it possible to use a nonlinear eddy viscosity model with the rhoSimpleFoam?

I am not sure if there is a model with that properties:

realizableKE, kOmegaSST, kEpsilon, RNGkEpsilon is for linear viscosity.
SpalartAllmaras is an one eqn model
laminar its clear

But LRR, LaunderGibsonRSTM and LaunderSharmaKE are what for models?
Linear or nonlinear?

Thanks for reading.
