Release Notes
This section contains information about the EDEM release, such as key features, enhancements, bug fixes, and known issues.
Tutorials
Start using EDEM functionality with our interactive tutorials.
Get Started with EDEM
The EDEM user interface comprises three icons for each simulation component - Creator, Simulator, and Analyst.
EDEM Creator
EDEM Creator is the pre-processor for creating an EDEM simulation model, including setting up equipment and defining the generation of bulk materials.
EDEM Simulator
EDEM Simulator is a powerful solver used for fast and efficient simulations.
EDEM Analyst
EDEM Analyst is the post-processor used to analyze and visualize the results of your simulation.
EDEM Contact Models
A Contact Model describes how elements behave when they come into contact with each other.
EDEM Cal Utility
EDEM Cal is a utility which works with EDEM and is designed to assist in performing calibration.
GPU CUDA Guide
The EDEM CUDA GPU module uses the latest General Purpose Computing on Graphical Processing Units (GPU) technology.
Programming Guide
The EDEM Programming Guide describes the EDEM API.
Coupling Interface Programming Guide
The Coupling Interface Programming Guide provides an overview of how to use the EDEM Coupling Interface to couple with a generic CFD code and/or Multi Body dynamics codes.
EDEMpy
EDEMpy is a Python library for accessing EDEM data from .h5 files (the underlying EDEM file format). EDEMpy does not require prior knowledge of advanced programming.
EDEM Solver Capabilities
EDEM contains four solver engines.
Appendix
This section provides additional information about how to estimate simulation time, supported EDEM File types, attribute definitions, and so on.
EDEM Terminology
Definitions of terms used in EDEM.
References and Bibliography
This section cites the contributions made by various authors and sources that have been used as reference material for EDEM, and the specifics of how they have been applied can be found in the individual contact model sections.

What's New

New features and enhancements available in EDEM.

Concave Polyhedral Particles

The EDEM Solver (CUDA) achieves another significant milestone with the introduction of full support for concave polyhedral particle shapes.

EDEM now fully supports all polyhedral particle shapes and allows them to be deployed in simulations alongside convex polyhedral, Multi-Sphere and Sphero-Cylinder particles.

Rigid Link for Fixed Particle Velocities

Rigid Link is a new boundary condition to assign the velocity from a Geometry section to a specified group of particles.

Normal and Lognormal distributions by Mass Fraction

EDEM has the ability to define normal and log-normal distribution by mass for particles and meta-particles which are generated from a factory or volume-packing.
