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)
