Hello everyone, I am currently using the immersed boundary solver interIbFoam with Foam-extend 4.0 to solve a question with RANS turbulence model. I have made the case according to tutorials and started the simulation. Then it comes out an error with boundary conditions of turbulence coeffeciants. The error message is showing below.
Code:
--> FOAM FATAL ERROR:

    gradientInternalCoeffs cannot be called for a genericFvPatchField (actual type immersedBoundaryEpsilonWallFunction)
    on patch ibCylinder of field epsilon in file "/mnt/g/foam/thomaschi-4.0/run/cylBumpInterIbFoam/0/epsilon"
    You are probably trying to solve for a field with a generic boundary condition.

    From function genericFvPatchField<Type>::gradientInternalCoeffs() const
    in file fields/fvPatchFields/basic/generic/genericFvPatchField.C at line 832.

FOAM exiting

Hi!


The problem relies on your boundary conditions. There is a boundary which is not consistent, so the simulation is under constrained.
