Hi all

I'm trying to simulate flow with free surface post a sphere. Distance of top of sphere from free surface is 0.15m. But there is a problem! i use opening boundary at outlet with pressure distribution as follow expression :
waterDensity*g*waterValumeFraction*(draft-zGolbal)
draft is a distance of free surface from origin.

but the streamlines near the outlet deviant up ( to free surf).
Whats wrong?

Best regards.
