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
