This book provides scientists and engineers with solutions to the basic problems of DEM modeling of granular solids, both conceptual and practical. To help new users, the book carefully follows important steps, from conceptual model, to the numerical simulation of dense granular materials. This includes contact models, numerical schemes, simulation setup and post-processing. The authors present many examples, including the complete code which assists the reader in reproducing the simulations with open-source code-Yade-DEM-that was developed by the author and his colleagues at the University of Grenoble.
- Presents the basics, along with effective usage of DEM code
- Details state-of-the-art, practical implementation for research and numerical methods
- Provides examples with scripts, linking the book to online content and freely available software (yade-dem.org)

Bruno Chareyre is Assistant Professor at Grenoble INP, in the department of Hydraulic Engineering and Geomechanics. His teaching activities include geotechnical engineering, structural engineering and numerical modelling. His research activities focus on Discrete Element Methods (DEM), the development of Yade, micromechanical approaches of the behaviour of granular media and homogenization, Fluid-solid couplings in unsaturated (capillary effects) and saturated (fluid flow) granular materials and Multi-scale approaches based on the DEM.
