Hi,

I have a simulation to run in which the ball in supposed o float in a cylinder filled with water. Somehow even after turning the gravity ON, Operating density=0, the ball doesn't float due to buoyancy.

Can anybody help me with setting up proper gravity,?

Another way i found was to introduce the net upward force(which accounts for buoyancy and weight of ball) on the ball in the UDF. But i am not sure whether tis is a correct approach. Any comments appreciated

FYI,its a dynamic mesh, 6DOF simulation
