Snow Plasticity MPM Simulation Demo 

Demo modeling a snow cube in freefall and colliding with a solid sphere using a Material Point Method (MPM) solver. Note that the lower the theta_s parameter, the more "powdery" the snow looks. Higher theta_s is associated with "chunkier" snow!
Conducted as part of 700-004 Physics Based Simulation at The University of Pennsylvania.
