For CFX:

Switch on the 'buoyancy' option on the fluid domain setting, set the gravity (x,y,z), set the reference temperature.


Remember to set the expansion ratio in the metarial box, and I think that's it.

I haven't use Fluent for quite a time now, but I think the setup would be more or less the same with this.
