Flip collision only from the inside of an object

[Doum]

Hey all,

 

I'm trying to fill an object(ie a sphere) with a source emitting from the outside, but once the liquid is inside, I want it to start colliding with the collision object na d stay inside. How can I acheive that ?

 

thanks

Here is one way to do it. Emitting particles in one solver without collisions, and if they are X amount inside the collision sdf we can add those to a group. We then emit those particles in that group in another solver with collisions. We also delete the original particles afterwards because we dont need them anymore, and finally we can combine both in SOPs.
