Hello! I've been playing with the unit vectors in Gravity definition for my VOF analysis (water & air sloshing). But I found the results of VOF behavior before & after changing to be EXACTLY the same. As if the changes in gravity e.g. -0.8i+0j-0.2k for a condition of 1.7G magnitude has no effect on water sloshing. We know intuitively that this is not true! (Default G unit vectors are 0i+0j-1k for 1G magnitude). So, my G vector definition could be wrong or is there something else I need to rectify in the settings to have this desired gravity definition?

Urgently please if anyone could help

Switch on Buoyancy for both phases.

beautiful! right on the dot! thanks i will try for both phases now.
