dp3D: DEM for materials science

dp3D is a 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. 
dp3D comes with a user guide with case studies that are starting points for simulations. Although the development is mainly at SIMaP, the code is open to external users sharing interests in materials science (contact: Christophe Martin)
