Default Turbulent dissipation rate in UDF
John Deas
Posts: n/a
In the k-omega SST, the dissipation rate of the turbulent kinetic energy is computed as:

Yk=rho beta omega^2

Is it possible to get beta in an UDF thus avoinding to recompute it, which can be a pain given the complexity of the structure of the k-omega model ?
