- Tutorial 1 - Conveyor
  This introductory tutorial covers the basics of EDEM and shows how to set up, run, and analyze a simulation.
- Tutorial 2 - Screw Auger
  This tutorial describes how to set up and analyze an EDEM simulation.
- Tutorial 3 Part 1 - Rock Box
  This tutorial covers the simulation setup suitable for using the Altair Student Edition. It can be established quickly and the simulation time is low (~2 minutes on 2 CPU cores).
  - EDEM Creator - Set up the Model
    Learn how to set up a simulation model and equipment, and define the generation of bulk materials using EDEM Creator.
  - EDEM Simulator - Run the Simulation
    Once you have set up the model, learn how to run fast and efficient simulations using EDEM Simulator.
  - EDEM Analyst - Analyze Your Results
    Learn how to review, examine, and analyze the results of the simulation using EDEM Analyst.
- Tutorial 3 Part 2 - Mixed Shape Solver
  This tutorial explains how this simulation is modified to be a high-fidelity model. This extended simulation requires a CUDA compatible GPU to run and is not suitable for the Student Edition.
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.

Tutorial 3 Part 1 - Rock Box

This tutorial covers the simulation setup suitable for using the Altair Student Edition. It can be established quickly and the simulation time is low (~2 minutes on 2 CPU cores).

Objective

The objective of the Rock Box tutorial is to:

Use the GEMM database.
Create multiple particle types and shapes.
Use mixed shapes (Polyhedral particles and Multi-Sphere).
Import a particle size distribution from a *.csv file.
Implement conveyor kinematics to the conveyor Geometries.

The model used in this tutorial is a rock box.

Important: You must download the simulation and associated CAD files ( rock_box1.stl,


                        Rock_Template1.stl

, Rock_Template2.stl, and Rock_Template3.stl) before starting the tutorial. In addition, a particle size distribution file is available (PSD.csv). It is recommended that you copy these files to the same location as the simulation files. To download the simulation files for this tutorial, see Download Simulation Files.
