Granular materials cover a broad area of research from soil mechanics and powder technologies, to soft materials, even pharmaceuticals. Despite the wide variety, the discrete granular structure is generic and it’s approach a simple integration of the equations of motion for all the particulates in the system based on the contact forces and external forces acting on the particles.

The goal here is to provide information on the various methods and components of discrete numerical simulations not only from the author’s line of work and experience but also from the collective knowledge gathered from research papers, presentations, and conferences.
