Hello dear cfd online folks

I am a mechanical engineer student who should finish his project very soon. One part of my project is analyze the technical drawing which is related to project and get the velocity analysis. It seems that i am lack of knowledge when the case is 3d geometry. So i made some simplification about geometry

Basically i design a unit volume and put two outlet which should suck 5m/s of air from the unit volume and throw it to atmosphere from roof. Thats all i need. So i put them upper side of my unit volume(that is also represent my roof boundary) and start solver but i couldnt get a reasonable solution at all. I both try outlet type and fan type for my air hole and they do not help.

I am open for any suggestion. I use "phoenics". Best regards.
