Help with convective heat flow

Problem: A non uniformly heated sphere is placed in the center of a spherical cavity (~10 times the diameter of the heated sphere) with fixed wall temperature and the intervening space is filled with low to moderate pressure gas (1 to 300 Torr). The system is in a gravitational potential. The gas settles into a convective flow that looks something like a toroidal pattern.
Question: Is the code ANSWER or ANSWER express (from ACRi - I think) a good code for this? Is there something better that can be run in a few days? I'm not a CFD expert; my background is in physics. I'd like to model this quickly. Thanks -- John |

One question is:
Does ANSWER allow you to include the radiative transfer? |
