I can't get the Monte Carlo Ray Tracing Model to run on my Fluent simulation
Here are the radiation settings:
And the material settings related to radiation for all my fluids:
I am using a realizable, k-epsilon viscous model with energy equation turned on. Aluminum, glass, and copper are present, but Fluent does not ask for material settings related to radiation. All cell zone conditions and boundary conditions participate in radiation, except for the inlet and outlets. A semi-transparent wall has thermal conditions set to glass (Calcium-carbonate) material - when I use either radiation or mixed here, the simulation still will not run. Mapped, coupled, and matched mesh interfaces exist here.
