Hi all,

I'm simulating water flow with a modified interFoam solver and a modified kOmegaSST turbulence model. Regarding the latter, the new omega values are calculated for some boundary patches within the solver during runtime.

I'm facing a problem with setting the right 'boundary conditions' for nut: I want nut to be calculated as nut =k/omega using my calculated omega values and k as zeroGradient.
Therefore I set omega as fixedValue in 0/omega and k as zeroGradient in /k. nut is deleted.

After decomposition of my case, omega and k values are still as described avobe. When starting the solver, nut is automatically created, which seems to be ok (or at least as coded). In that step, the solver unfortunately sets omega to omegaWallFunction (instead of fixedValue) and k to kqRWallFunction (instead of zeroGradient). How can I achieve the correct behaviour?

Greetings,
Arne
