High-Resolution Simulation of Granular Material with SPH

We present an efficient framework for simulating granular material with high visual detail. Our model solves the computationally and numerically critical forces on a coarsely sampled particle simulation. We incorporate a new frictional boundary force into an existing continuum-based method which enables realistic interactions and a more robust simulation. Visual realism is achieved by coupling a set of highly resolved particles with the base simulation at low computational costs. Thereby, visual details can be added which are not resolved by the base simulation.
