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:

Code:
LRR
LaunderGibsonRSTM
LaunderSharmaKE
RNGkEpsilon
SpalartAllmaras
kEpsilon
kOmegaSST
laminar
realizableKE
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.
Tobi
