Hello,

I'm currently working on some modifications to the interDyMFoam solver. I am trying to understand how the displacementLaplacian motion solver works, and I'm hitting a few walls.

I'm using OF 2.4.0 (no reason why I'm using this over 4, It was just the version I had when I came back to openFOAM and started reading into this solver). I'm also new to object orientated programing so a lot of my confusion could be coming from that.

I'm trying to understand how the function
pointDisplacement_.boundary().updateCoeffs(); works. To do this, I'm stepping through the code using gdb as well as navigating with the doxygen source code guide.

so the function is defined in GeometricBoundaryField.C, in the code snippet below.

template<class Type, template<class> class PatchField, class GeoMesh>
void Foam::GeometricField<Type, PatchField, GeoMesh>::GeometricBoundaryField::
updateCoeffs()
{
    if (debug)
    {
        Info<< "GeometricField<Type, PatchField, GeoMesh>::"
               "GeometricBoundaryField::"
               "updateCoeffs()" << endl;
    }

    forAll(*this, patchi)
    {
        this->operator[](patchi).updateCoeffs();
    }
}

The problem I'm facing is I cant get to the definition for updateCoeffs(). GDB takes me through I think operator[](patchi) when i use step (s) on this line of code.

So if anyone could point me to the declaration for updateCoeffs() or maybe knows how to choose which function you step into with gdb, that would be fantastic

Cheers
