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 manual 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)
