Hej,

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

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

Code:
void nutkWallFunctionFvPatchScalarField::updateCoeffs()
{
    if (updated())
    {
        return;
    }

    operator==(calcNut());

    fixedValueFvPatchScalarField::updateCoeffs();
}
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

I am also wondering about the difference between the nutWallFunction and the nutkWallFunction. Does anyone have an idea?

nutWallFunction is a virtual base class.
