Radiative Cooling of a Cube in Vacuum (Satellite Simulation)

Please login with a confirmed email address before reporting spam

I’m having trouble setting up radiation physics in vacuum. Specifically, I have an aluminum cube representing a satellite in space, initially at a temperature of 393 K. It needs to cool down by radiating heat to the surroundings, which are at 93 K. How can I set this up? Thank you!
