I'm trying to make a simulation where a chocolate and almonds are poured with almonds colliding with each other. 
I made the flip sim and extracted the velocity field to advect the pieces, but for some reason it didn't work. 
What am I doing wrong? 
I'm still a beginner so keep it simple please .

Unfortunately, the setup is not simple. Here's about as basic as you can get. Unpacked RBDs hang out inside a flip volume, being affected by it.
