Simulating particles & liquid in a cyclone

[JuhaHo]

Have you set the container as a collider (using a PhysX Collision op if your particles are PhysX particles)?

Alternatively you can use a Surface Test to do an inside/outside test and delete any rogue particles that escape.

Thanks,

I was suggested earlier to give up PhysX and use tyFlow operators instead. So I'm using tyFlow Collision, Force (gravity) and Fluid Force.
