dp3D user guide

This is a guide for using the dp3D DEM (Discrete Element Method) code dedicated to materials science. dp3D is an in-house code used for the numerical simuation of processes involving powders, and more generally for investigating the behavior of materials with a focus on brittle fracture. It comes with a series of contact laws that are useful for these domains (elasticity, adhesion, plasticity, sintering, bonding, fracture, continuum models, ...) and includes thermal conductivity.
