Hej;

I have questions about the interfaceProperties class. What does

nHatf_

really present? It says something about a flux?

Also:

in the function calculateK()

in the first two lines

00101     const fvMesh& mesh = alpha1_.mesh();
00102     const surfaceVectorField& Sf = mesh.Sf();

some kind of mesh is created from alpha1, if I understand this correctly. What does this mesh represent? And is it possible to read do something like

surfaceScalarField& alphaAreas = mesh.magSf() ;

to retrieve some kind of area from the mesh, and if it is an area, is it the area of the alpha1 boundary within a cell?

If this does not work, is it possible to get the interface area between the two phases somehow else?

Thanks in advance!
