Default sos! How to define the flow rate of outflow BC?
Posts: n/a
Hello, everyone,

My research model has 2 inlet and 2 exits. I gave the velocity inlet BC to the 2 inlets, which correspond to two kinds flow rate waveforms (this is an unsteady problem). Then I need to define the two outlets as fully developed with certain flow rate waveform. It seems that outflow BC can keep the flow at exits fully developed. However how to give the flow rate waveform (transient flow rate) at exits at the same time? The outflow BC seems only support the constant flow rate distribution.

Would you please to give me some advices on it?

Thank you for your time! Regards, Junmei
