I have a dozen small balls dropping down onto a tub of FLIP fluid. The balls have a radius of .25 and a density of 0.00001 . My Flip fluid has a density of 1,000,000 and a viscosity of 10,000,000.
And yet when I drop the balls into the fluid they drop to the bottom. Wtf? Shouldn't they float on top? Is the illusion of surface tension messing me up?
How do I get RBD objects to float on FLIP fluids?
See attached Houdini 12 file for the cause of my tears.
