Pressure outlet problem

IronMike · February 1, 2010, 05:50

Hy everybody, i am modeling the flow inside car, and the outlets i considered pressure outlet boundary. The problem is that when i want to plot the pathlines, exist also pathlines released from outlets to the interior of the vehicle; in real life this problem does not exists.
The question that i want to be asked is that the pressure outlet is a good bc for that type of flow or should i use something else. Also, if i put another pressure at oulet bc this will create depressurization, because the pressure will be bigger at the inlet, and smaller at the outlet.
What do you think?

Thanks a lot!
