Chute flow simulation & experiment with 1 million spheres:

method: Moreau time-stepping with unilateral contacts and Coulomb friction
computed on 384 cores with GRSFSimMPI in 12 h, rendered with GRSFConverter and prman in 24 h.
time step: 0.0002 s, friction coefficient: 0.8
restitution coefficient: 0.0 (fully inelastic impacts)
global contact iterations: 1000
