Default Flux across cyclicACMI coupled patches

Hello,

I am developing an HLLCL solver for an application that requires a cyclicACMI interface.

I have attempted to develop this solver using an approach similar to rhoCentralFoam but believe I have run into this https://bugs.openfoam.org/view.php?id=2561 issue.

I have also attempted to use a similar approach to the dbnsTurboFoam solver included in foam-extend but run into a problem when looping across coupled faces.

The scalar field returned by p_.boundaryField()[patch index].patchInternalField() or p_.boundaryField()[patch index].patchNeighbourField() includes both coupled and uncoupled faces (with zero values). Is anyone familiar with the appropriate way to deal with this. I assume I need to loop over the coupled faces with appropriate weights (assuming multiple faces are coupled at the same time) and probably don't need to loop across each of the (4) boundary fields required for the cyclicACMI?

I am running openfoam-7.

Thank you for any assistance you may be able to provide.
