Hi,

I am doing VoF simulation with rectangular domain. I filled half of Water half of Air as shown in figure.

I applied the following boundary conditions:
Inlet : Velocity Inlet
Outlet: Pressure Outlet

The issue is After certain time the water level at the outlet is slowly decreasing as well as in domain also. What should be the reason to fall down water level ?

Thanks in advance

Hi svenki7,

Could you upload the velocity field in the domain? By the way, where are the locations of the inlet and outlet.

The following inlet and outlet positions
