Full Article:

We present 3D numerical simulations of the collapse and spreading of granular columns based on non-smooth contact dynamics and conic programming. A novel rolling resistance model is developed which can model non-spherical particles using spheres at a lower computation cost. The simulated final heights and run-out distances are in good agreements with experimental studies.
