Hello, I'm currently trying to simulate turbulent flux of air (model k -epsilon) in a room.

This room has two inlets of air (similar to an air conditioner) where there's air flowing inside the room and underneath air being sucked from the environment, just like a real split model.

My problem is how to set the BC of this outlet that sucks air continously from the environment. Currently I'm using for U and P:

For U:

outlet
    {
        type                flowRateOutletVelocity;
        volumetricFlowRate  0.2;
        value               uniform (0 0 0);  
    }

For p: 

outlet:
    {
        type            zeroGradient;
    }

I'm starting from the principle that the BC for a sucction area is supoused to be equal as an inlet of air blowing into the envioronment. What i'm missing??

Thanks in advance!!
