Welcome
About EDEM
EDEM is a high-performance simulation software for bulk and granular materials.
What's New
New features and enhancements available in EDEM.
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 File Types
  This section lists the EDEM file types, including Standard and Optional supported file types.
- Estimate Simulation Time
  It is challenging to estimate the exact real time required for a DEM simulation, as each simulation and each computer is different.
- Attribute Definitions
  The following tables provide detailed descriptions for Particle, Geometry, Contact, and Collision attributes.
- Calculate Characteristic Length
  The Characteristic Length is the average length of each feature in the CAD file.
- Use EDEM on a Remote Desktop
  Generally, simulations are set up on Windows. However, the simulation is run on a Windows or Linux processing machine which is remotely located.
- Command Line Example Commands
  This section provides examples of the default processing options, and how to specify processing options and run simulation and export data.
  - Replace Geometry from the Command Line
    The Replace Geometry command requires a configuration file that contains relevant information for each Geometry which is being replaced.
  - Run Dynamic Domain
    This section explains how to run Dynamic Domain from the command line.
  - Data Export Options
    In any EDEM simulation, you configure the export data settings in EDEM Analyst.
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.

Replace Geometry from the Command Line

The Replace Geometry command requires a configuration file that contains relevant information for each Geometry which is being replaced.

The format of this file is as follows:For each section to be replaced, include a line formatted where the delimiter is the '#' character:

<cfg file section> # <target section name> # <CAD file> # <import units> # <Geometry material> # <mesh (y/n)> # <Min Size/Element Size> # <Max Size> # <Max Deviation> # <Max Angle>

If you use the meshing option n, the default mesh import options will be used.
If you use the meshing option y, the number of arguments after the y will determine the approach used. A single value will use the Size and Bias approach, and four values will use the Rigid Body approach.
Example
The cfg file section is a unique identifier for each object. You can assign any value provided that it is unique to any other cfg file section used in the file.
```
Section1 # guide 1 # D:\Wall21.stl # m # steel # n Geometry will be imported using default mesh options
```
```
Section2 # guide 2 # D:\Wall22.stl # mm # steel # y # 10 Geometry will be imported using size and bias approach and Element size 10mm
```
```
Section3 # guide 3 # D:\Wall23.stl # mm # steel # y # 10 # 100 # 1 # 15  The Geometry will be imported using the Rigid Body approach and the four parameters shown
```
Reference the config file from the command line as follows:
```
edem.exe --console -i td.dem --rg rgconfig.txt -R
```
