Hello Everybody,
is it possible to simulate a chamber with just an outlet to see how the pressure changes by evacuating the chamber with a pump?
I know the mass flow at the outlet. But when i say there is a specific Outlet mass flow the simulation got an error in the X-momentum.
Is it even possible, because simply say i take mass out of the chamber so the density and pressure changes. How can i do that? Or is it impossible due to mass imbalances? I´m not afraid of UDF if it´s necessary.

I didn't find the right solution from the Internet.
