Volume Fraction vs Velocity????

Hello, I've been working with a model of a tank in which water is coming in from the top and getting out trough a pipe.

When I plot the contourn of volume fraction of water, it shows me that the pipe is partially full because the vf of water is zero at about 30% of the pipe's diameter. However, when I plot the contourn of velocity magnitude, it shows me that the pipe is full becouse I have velocity values around the whole diameter. If the volume fraction is zero at any point, how the velocity of that fluid can be more then zero?

As information: - Inlet BC: Vel.Inlet - Outlet BC:Pressure Outlet - Top of the tank BC: Pressure Outlet

Thanks a lot

Humberto

No, I'm not working on it.
