**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
