Hi,

I want to simulate such a case by Fluent:

A cylinder with saturated or unsaturated soil. The top boundary condition is isothermal (300K) and permeable. The bottom B.C. is isothermal (350K) and impermeable. The lateral walls are insulated and impermeable.

Question 1. How can I set the top B.C. in Fluent? I used the pressure outlet B.C. for the top surface, while the results showed the temperature at the top is not a constant.

Question 2. For the pressure outlet B.C. in Fluent, does the backflow has the same property of the fluid used in the interior?

Thanks a lot.
