my goal is to calculate some effects in cold atoms due to blackbody radiation. Atoms (in a trap) are in ultra-high vacuum in the center of a (mostly aluminum) vacuum chamber. There is air outside the chamber and the chamber is heated in a few points. I have the model of a chamber made in SolidWorks. Now I would like to calculate with Aurora the steady-state temperature distribution on the chamber (particularly on the inner surface) and I think this is possible with Aurora. Then I wolud like to calculate the blackbody radiation from the chamber surface in the place where my atoms are, e.g. on a very small (probe) surface. Is this possible with Aurora? Or do you know any other free software being able to do this?
