Hello,nHere are the answers:na. No, you cannot parameterize mass flow rate from the Periodic conditions panel.nYou have to define a pressure gradient [in Pa/m] in the periodic conditions panel. This gradient would give you a pressure drop, which will be constant across the periodic faces. Also, this cannot be parameterized.nWhat values are you using? How are you estimating the average velocities? What is the area at the inlet boundary?nTo estimate temperatures, I'd use the mass-weighted-average values at the periodic faces (inlet and outlet). Regarding your other point, this is correct. The total input heat flux must be equal to the sensible heat carried by the fluid.nPlease let me know if you have any additional questions.nKarthikn
