Hi,

I am simulating steady-state heat transfer inside the packed bed system. For that, I have specified mass flow inlet boundary condition at the inlet. At the inlet, mass flow rate and inlet temperature of 800 K has been specified. At the wall, heat flux is applied. At the outlet, pressure outlet boundary condition has been considered, where zero pressure is specified.

My query is about the backflow temperature at the outlet (by default 300 K is given). What shout be the backflow temperature specified. Is there any way to choose this temperature? or it should be by default 300 K?
