i am trying to do a simulation with real world scale.
i has always been successful with this kind of sim using “fake/bigger” scale earlier.

I would like to know what am doing wrong here, even when i crank up the collision geometry sub and the solver steps i get interpenetration and it looks really odd, unreal
I am using rbd solver and not bullet as the glass will be filled with flip fluid.
I find the rbd to play nicer with flip over bullet.
tell me if am wrong.

here is the file

thank you
