Suction simulation

I would like to simulate the suction on an airfoil using fluent 

the airfoil diagram is shown below, there is a suction slot which the sucked air flows through that leads to the low-pressure cavity which causes the suction.

The idea is to induce high energy turbulent mixing in the boundary layer flow and delay/prevent flow separation, thereby preventing stall

How do I simulate this environment in ANSYS Fluent.

please check this

though its old, it will help you get through process.

I don't see any tutorials on how to create suction.

I just need to know how to create a low-pressure environment in the suction cavity i.e. how do I specify boundary conditions that create a low-pressure environment?
