gustavosimiema is on a distinguished road

Im new with Fluent. I would like to simulate the flow behaviour of a mixture gas inside a vacuum chamber. The process is: the pumping (air) of the chamber from atmospheric pressure until 1 PA. After this pressure been achieved, there will be 20 gas inlet (2mm Diameter) and will inject a mixture of two gases (O2 and N2). Also will be an outlet where the gases will come out through the pump keeping the pressure in 1Pa.
As far as I could understand, I can use the laminar model. But I could not make an Animation of the air pumping and consequently the gas mixtures inlet showing the behaviour of the gas flow in this condition from the inlet until the outlet.
Could anyone one give me some hints? How I inform the Software that my Initial condition is the chamber full of air and then the pumping starts until achieve 1Pa?

P.S. Im dealing with a big chamber of 3m3 volume.
