Pressure inlet works as an outlet

Hey
I gave the fan inlet the function of pressure inlet 50 Pa in convective heat transfer. The the fan at the bottom and in the middel give a positive velocity inlet. The fan inlet at the top have a negative velocity, altough they are all on the same side of the building. I also can change the setup from totale gauge pressure.

Do you know how i can fix this problem? I don’t know the velocity needed to create the pressure.
It is the last simulation (Final_Convectiveheattransfer_…)

This is the link to my simulation:

Thank you in advance

Kind regards

Hey there, I guess this is the run you are referring to?

All three runs have by area averages → fan inlet → in the plot that result

Hi there, would you like to provide some information regarding how you resolved this? :smiley:

Best regards,
