Default UDF for turbulence models

Hello all,

Can a completely new turbulence model be implemented with a UDF? Specifically I'm interested in the zeta-f, v2-f, and RSA models.

My understanding so far is that it is possible to do the zeta-f and v2-f models because they also use the original k-epsilon transport equations. However, in the RSA model, k and epsilon have algebraic relations and are not defined by transport equations. Since this is a different implementation of k and epsilon I'm unsure if the use of a UDF is possible for the RSA model.

Any insight is appreciated,
Tim

You may could model it by entering sources, changing variables in turbulent models panel. Or, write two user defined scalars for turbulent parameters.
