Hi, I would like to use flow simulation as part of a high school project.

I have to simulate air flows in a greenhouse.

The greenhouse has two fans that bring in air and two fans that blow out the air.

All fans are identical.

I was able to simulate both input fans (using conditions at the input speed limits) but could not simulate the air outlet (I tried using conditions at the air outlet limits), flow simulation asks me to add a condition to the limits for gold pressure I have no openings other than fans

Thank you for your help and excuse me for my English.
