Hi,

I would really appreciate it, if anyone can tell me how to find the number of cells adjacent to a patch. I would like to loop around the cells for my boundary condition.

Thanks

You can probably use something like this :

        Foam::label patchI = mesh.boundaryMesh().findPatchID("patch");
        const Foam::fvPatch& currPatch = mesh.boundary()[patchI];

	forAll(currPatch,facei){
	    face faceI = currPatch[facei]; //face
	}

        const labelUList& faceCells = currPatch.faceCells();

        Info << "number of adjacent cells : " << faceCells.size(). //number of adjacent cells

I've not tested this, but I tried to piece together code that exists elsewhere in OpenFOAM. In any case, a forAll loop can be used to loop through patch faces and faceCells lets you access adjacent cells.
