Hello all,

I am trying to program a new wallfunction which is interacting with the kEpsilon model. Depending on values calculated in my wallfunction, the turbulence model needs to choose between two functions for calculating Epsilon and return it to the wallfunction.
I am looking now for a Sequence Diagram or something similar to understand the correct timeline interaction between the wallfunction and the turbulence model, can anyone help?

Thanks very much,
Julian

I am not really sure, but I think it is done this way:
The values for the wall are calculated in the in wall boundary condition, e.g. in nutWallFunctionFvPatchScalarField.C in updateCoeffs(). Then in the turbulence model, e.g. kOmegaSST.C, in correct() this function is somehow called (there is e.g. a call to omega_.boundaryField().updateCoeffs() and the values used for the equations (k and omega).

Hope this helps (and is not much too late).
