problem of temperature boundary conditions
 

Hi everybody,

I am trying to model the cooling of a server in a room. I have an air flow in the room and I want to put one side of the rack as an outlet and the opposite side as an inlet. Until this point there is no problem, but I want to have the temperatue at the inlet side equal to the temperature at the outlet side of the rack plus a delta T (fixed).

if someone can help me.
