Thanks for your reply. Below figure is the profile of my geometry. Because it includes full-pipe flow and open channel flow simultaneously, I didn’t use open channle flow function in VOF setting. And I don’t know the water depth at outlet boudary before the simulation either, and can’t give an estimation of proper gauge pressure for pressure outlet boundary. That’s the reason why I was thinking about outflow boundary condition. Any suggestions would be appreciated.
