Hello guys!

I havent really ever worked with top, but i guess i have to now. I want do a fluid simulation and then use the result as a collision object in another fluid simulation and so on. I believe i have to use a feedback loop for that but i have no idea on how to use it. If anyone had an example file to share that would really help!

Cheers,

Nico

There's an example shipped with Houdini in $HFS/houdini/pdg/examples/top_feedbacksim that you may find useful. It's uses a feedback loop with an RBD sim that runs for each iteration of the loop. The last frame of each RBD sim for a given iteration is used by the subsequent iteration as a static collision object.

Thanks alot for the quick response! I will try it out immediately!
