Hello!
I use laplacianFoam with boundary conditions to get temperature field in the model. However, there are several cavities (1 and 2 in the radiation.png) so it's necessary to account radiation. External heat fluxies at the boundary qw are known.

I want to use ViewFactor or fvDom radiation models but I don't understand how one of them should be added into solver. It would be great if anyone give me an advice.
Thanks in advance.
