Chrono DEM module tutorials

The Chrono distribution contains several demos for granular dynamics with the DEM module.

Chrono::Dem provides support for GPU-accelerated granular dynamics via the penalty-based discrete element method (aka SMC).

Granular dynamics demos:

• demo_DEM_ballCosim

  A simple co-simulation example: A large sphere represented as a triangular mesh interacting with granular material. The dynamics of the sphere are performed by ChSystem, with contact forces generated from the Chrono::DEM system.

• demo_DEM_fixedTerrain

  A terrain initialization utility that generates fixed particles on a surface mesh of the terrain and load additional particles from the above.

• demo_DEM_movingBoundary

  A settled container of granular material is shoved to the side by a moving boundary plane.

• demo_DEM_mixer

  A cylindrical container with a rotating blade that mixes granular material.

• demo_DEM_repose

  Granular material flows through a hopper funnel and forms a stable pile, demonstrating the angle of repose.
