Air suction with Flowsimulation

Hello !

I'm currently working with Flowsimulation in order to make a simulation of air suction through a simple pipe first. To do that, I've created a box in which I put a simple tube. But I recently discovered this software and I'm not able to make it aspire IN the tube. Indeed, I try to impose an input speed to the tube (boundary condition) and the environment pressure inside the box (other one) but I can't tell the software to take the area inside the tube to make the fluid pass through it : the suction is done around the tube because the only surface available is the thickness of the tube which is considered as an external face (and I'm working with internal analysis) ...


Could somebody explain to me the process to do that ?
