Well,

-solver>unsteady>1st order implicit -multiphase>VOF>implicit body force ON -if you have baffles inside, SLIT THEM! -set the lighter phase as phase-1 OP CONDITIONS -turn on gravity, be careful about the signs of the components -operating density, the one of the lighter phase -pressure location: a point where the lighter phase is. SOLUTION -U-R Factors: pressure 0.6 momentum 0.8, 1 the others. -discretization: body force weighted for pressure, PISO for pressure velocity coupling (PISO parameters: skewness correction 0, neighbor correction 1), first order upwind for momentum.

initialize the flow field, and then

-adapt>region set the coordinates where water is and click mark. -solve>initialize>patch: under phase choose water, under variable volume fraction, under value 1, under registers to patch the region you marked, than patch.

Basically that's what is it.

hope it helps,

Edi.
