Simulating duct with multiple inlet using FLOWUnsteady

[King-of-Avon]

Hi all,
So far, I have only seen FLOWUnsteady used for rotors and wings. Is there a way I can simulate flow through a duct with multiple inlets, and especially variable inlet velocities? What are the vehicle definitions I would require to make this happen?

I would greatly appreciate it if someone could point me to the right resources.
