Default modelling negative pressure

Hi CFD Experts:

A little help?

i'm looking to model a fluid domain (air) that has a air supply and extract in the space.

The extract levels are 4 times as high as the inlet.

Do i need to run a transient simulation here, as there will never be a steady state reached ? as the air pressure in the space will be increasingly negative?

Any advices appreciated

-ted
