Unified Particle Physics for Real-Time Applications - SIGGRAPH 2014

We present a unified dynamics framework for real-time visual effects. Using particles connected by constraints as our fundamental building block allows us to treat contact and collisions in a unified manner, and we show how this representation is flexible enough to model gases, liquids, deformable solids, rigid bodies and clothing with two-way interactions. We address some common problems with traditional particle based methods and describe a parallel constraint solver based on position based dynamics that is efficient enough for real-time applications.

that is truly insane... so how do we get to download this? or is it used in games ?

 

FLEX isn't available yet but you can run it independent like APEX or through PhysX 3.4 when available.
There was a quick Q/A when FLEX was announced if you're interested:
