holv0929 is on a distinguished road

I am trying solve a hyrodynamic problem. A circular cylinder with two bladder at each end is under seawater, and I am trying to simulate the rotation of the cylinder which is driven by BuoyantForce from the bladders. But I cannot find out how to set a such condition that density varies by depth
