I want to inflate a balloon underwater. When I merge Vellum Solver with the FLIP Solver, the former is not affected by the collision. Can anyone explain why is that? There have been already several unanswered questions about this[1 [forums.odforce.net], 2 [www.sidefx.com]].

can you visualize your collision geometry to see what they look like?

Collision geo is fairly simple and not really relevant. What I'm trying to achieve is to group flip particles after they reach certain Y position and choose different collision geometry for them or something like that.

I want to create a closed system in which water will be sucted from one container to the other. In the attached image I created two boxes with holes and 2 curves to which I applied a POP curve force. I simply used static solver for the collisions. How do I prevent the fluid from leaving the container after it's inside? I have little experience with flip sims.
Thanks
