This eBook describes the theoretical background behind the Discrete Element Method (DEM) - a particle-scale numerical method for modeling the bulk behavior of granular materials and many geomaterials such as coal, ores, soil, rocks, aggregates, pellets, tablets and powders.

The following topics are covered:
- Modeling Approaches
- DEM Background
- Particle Motion Calculations
- Time Steps
- Interaction Models
- Contact Detection
- Particle Shapes
- Material Calibration
- Geometries in DEM
- Coupling DEM with other CAE tools
