Dear Foamers

As I'm new to openfoam, I've became so confused to find values of neighbor cells of a patch for a volScalarField.

These two ways I thought can be useful give me wrong values:

My volScalarField is CH and patch name is interface:

1.
const label patchInterface=mesh.boundaryMesh().findPatchID("In terface");
fvPatchScalarField& CHface=CH.boundaryField()[patchInterface];
const labelList cl=CHface.patch().faceCells();
forAll(CHface, facei)
{
Info << CH[cl[facei]] <<endl;
}

2.
scalarField CHF=CH.boundaryField()[patchInterface].patchInternalField();
forAll(CHface, facei)
{
Info << CHF[facei] <<endl;
}


These two codes give me correct value for 2 or 3 first iterations but after that they start to grow in a wrong way and diverging after about 10 iterations.

Would you be kind enough to suggest me a new solution?
Thanks in advance

The first version our the values on the face cells whereas the second version should give you the values of the cell centers for the cells next to the face.
