Simple natural convection question from novice
 
I must preface by saying that I am completely unfamiliar with fluent, and will likely ask questions reflecting that.

I am trying to determine the resulting fluid circulation in a box with uniform temperature of the top and sides, and a spatially varying temperature on the bottom.

How do I set these boundary conditions?

Thanks

Is it a 2D or 3D? If 2d then so easy. You have to write a UDF for bottom BC....
