How to setup radiation boundary condtions in dem?

hello everyone, I have met a problem: is the mifx-dem can give a specific BC that can offer a radiation boundary condtions, so that i can simulate the particles heated by the sunshine?
And what should I do?

MFIX-DEM does not have a radiation model. There is a “third party” model, although we don’t support that. See this thread: Add a P1 radiation model to the DEM simulation
