What kind of Boundary conditions (Pressure, No slip...) must be imposed over a closed tank (in 2D) with a hole in its base to perform a simulation of a exit jet due to gravity (static pressure)... my domain is a rectangular tank and under it a rectangular domain which simulates free space (the elements which are contained in the tank are filled with fluid -volume fraction equal to 1 at time t=0) The problem is to be solved using ANSYS /FLOTRAN and VOF algorithm thank you.

just turn on the buoyant option and give gravitational accn. and intialize the domain with fluid vof = 1 and do the iterations.
