Hello everybody,


instead of using mixture.surfaceTensionForce() on the right side of UEqn.H, I want to calculate a slightly different term "by hand".
Therefore, I took the implementation of the surfaceTensionForce and replaced just the second addend:

solve
(
    UEqn

==
    fvc::reconstruct
    (
        (
            ...
          + fvc::interpolate(interfaceProperties::sigmaK()) * ...
            ....

        ) * mesh.magSf()

    )

);

It doesn't work, the following error occurs:

error: cannot call member function 'Foam::tmp<Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> >Foam::interfaceProperties::sigmaK() const' without object

Calling sigmaK() with mixture.sigmaK() or interface.sigmaK() does not work too. Do you have another idea?


Thank you!

Ok, I found out that it works with fvc::interpolate(mixture.sigmaK()). No idea why it did not work 1000 times before
