Hello Everyone,


I am modelling kEpsilon Turbulence model in chtMultiRegionSimpleFoam. I included alphat in my parameters but I don't know, what boundary conditions to use for it. My boundary conditions for other parameters were working fine, but when I included alphat in my system/changeDictionaryDict, I am getting the following error:

--> FOAM FATAL ERROR: 
cannot be called for a calculatedFvPatchField
    on patch inlet of field U in file "/home/openfoam/run/final_geometry_turbulent/0/fluid/U"
    You are probably trying to solve for a field with a default boundary condition.

    From function Foam::tmp<Foam::Field<Type> >  Foam::calculatedFvPatchField<Type>::gradientInternalCoeffs() const  [with Type = Foam::Vector<double>]
    in file fields/fvPatchFields/basic/calculated/calculatedFvPatchField.C at line 187.

I don't know where is a mismatch between the boundary condition? OR is there something else I am not doing correctly?


Any help would be highly appreciated.


Thank you
