  Hello Everyone,
  
  I'm trying to create simple transient simulation of pumping out air from the box. How can I achive that? What should I define in outlet of the box? Should it be preasure set for 0? Is it any way to determine preasue inside of box at the start of simulation?

  I assume you're running transient? What is the gas density set at?

  Hi Rob,
  Yes, I'm doing transient simulation.
  Gas density - I took air from library, density constant = 1.225
  
  Best Regards Mateusz
