Hi Foamers,

I'm trying to find what processor a particular cell neighbours with. I've found that his may be done by looping over all boundaries, finding those of type processorFvPatch and then accessing the faceCells() list. To get the processor index I've found the processorFvPatch::neighbProcNo() method.

I have a problem with getting the number of the domain the patch neighbours with. In the code given below I get an error:

error: ‘const class Foam::fvPatch’ has no member named ‘neighbProcNo’

Clearly, I'm not accessing the derived processorFvPatch but the base fvPatch type. How can I overcome this? It seems trivial but I've already spent too much time dwelling on this so I thought I'd ask.

forAll(mesh.boundary(),patchi)
{
    if (isType<processorFvPatch>(mesh.boundary()[patchi]))
    {
        Pout << mesh.boundary()[patchi].name() << " " << mesh.boundary()[patchi].neighbProcNo() << endl;
    }
}

Many thanks,

A

For those interested, here's the solution:

const processorPolyPatch& pp = refCast<const processorPolyPatch>( mesh.boundaryMesh()[patchi] );
Pout << mesh.boundary()[patchi].name() << " "  << pp.neighbProcNo() << endl;
