Hi everyone. I hope you are well. I want to simulate 2 phase flow with interFoam solver and I want to impose constant pressure difference during my simulation. I know that I should use fixedValue for pressure boundary conditions at the inlet and outlet but but I don't know which velocity boundary conditions is suitable for my problem.
I would like to ask you which pressure and velocity boundary conditions are suitable for my problem and how can I apply a constant pressure difference during the simulation.
I would be grateful for any assistance you could provide. Thank you for your time and consideration.

Best regards,
