Acess the neighboring region in multi-region problem

saumavadey · July 23, 2021, 12:42

Hello!

I am developing my own multi-region solver in OpenFOAM where I need to identify the neighboring solid regions of a particular fluid region and vice versa.
Would anyone please help me with any leads on how to achieve that?

Access would be done on the boundary, correct?

I am trying to access the patch values of the field 'h' for a region from it's coupled patches. The snippet of the code looks like this:

forAll(mesh.boundaryMesh(), patchID)
{
if (isRegionPatch(patchID))
{
forAll(h.boundaryField()[patchID], faceID)
{
qINT[faceID] = qINT[faceID] + h.boundaryField()[patchID][faceID];
}
}
}

I think the use of the function 'isRegionPatch' is incorrect. Can anyone provide me with the correct usage of the function 'isRegionPatch'?
