Hey hi,
I am experimenting with the internal flow feature to simulate a flow inside a grooved duct. I am setting the inlet total pressure and the required outled mass flow rate. Even though that the flow velocity across the cross section of the part appears to indicate the right mass flow rate, upon creating a goal plot the global mass flow rate is either unrealistically small or even at some cases becomes negative unlike the velocity field which appears to be correct!
Any ideas?
Cheers
The global goal for flow or mass is monitoring that the flow in minus the flow out is small or ideally zero. It is a conservation of mass thing. Use a surface goal to get the flow rate or mass flow in or out of a port.
