How to define an initial pressure inside a chamber in Fluent?
I am working with a chamber that is supposed to be a low vacuum chamber ( ~10^-3 mbar) where the working gas enters. I am a bit confused as to how can I set this pressure inside the chamber. as the chamber is my principal flow domain, should I set the pressure using the operating pressure option? Note that I am working with incompressible flows where density does not change.
