hey im simulating a multiphase flow in an open tank with outlet to pump suction pipe and inlet from the side of the tank. about 2/3 of tank is filled with water and the rest is air. its like a steady flow. i have a problem that my flow is not making a lot of sense with the water is jumping to the top of the tank. i set the boundary conditions with velocity inlet in the side, pressure outlet at the pump suction, and pressure outlet at the top with atmospheric pressure. please, anyone, i need your help.
