I have been looking into the nut wall function behavior and found that there are two different nut wall function boundary conditions, one called

and the other one
for some reason there is almost no difference, just that in the function

void nutkWallFunctionFvPatchScalarField::updateCoeffs()
    if (updated())


the if(updated()) is added to the nutkWallFunction but not to the nutWallFunction. Does anyone know why there is a difference and what it does?

I don't know the difference; however, I'm running openfoam 2.0.1 and there is no nutWallFunction available, only nutkWallFunction
