I have a reasonable idea of what kind of PDE's might allow us to model and simulate fluids, or elasticity, but what do they look like when we're trying to simulate something like snow? Intuitively, we need "clumping", but what is this like at the mathematical/PDE level?

@Kalecgos Well I suppose you just have to read the paper "A Material Point Method For Snow Simulation". ;-) The equations used to simulate snow physics are listed in Section 4, and involves using "particles (material points) to track mass, momentum and deformation gradient."
Also, I'll point out that the paper mixes both Lagrangian & Eulerian representations to simulate snow, an approach briefly mentioned in this slide.
frozen 2 looks really good!
