Tutorials
Start using EDEM 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 Physics 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.
- Load a Deck
  The first step in setting up a calibration run is to load in a prototype EDEM deck. The deck should be configured so that they can be executed from the command line.
- Post Processing of Simulations
  EDEM Cal allows automated post processing of simulations based on a pre-configured data query from EDEM Analyst and an EDEMpy script.
- Submit a Job
  EDEM Cal is a Windows-only application that can generate a batch job for Linux. The EDEM Cal utility allows you to submit a job to alternative computers on your network or on the cloud using the input files from EDEM Cal, and all the job-related files such as input, output, and logs are copied back to the EDEM Cal utility once the job is complete.
- Parameter Editor
  The Parameter Editor allows you to modify the parameters once the deck is loaded. The parameters that you can modify are: Particle-Particle interactions, Particle-Geometry interactions, and Physics model parameters and options.
- Analyze Results
  The Results Analysis section of EDEM Cal combines all the results files into a single csv file.
EDEM Calibration Kits
The EDEM Calibration kits are a collection of EDEM models of standard bulk solids characterization tests commonly used for EDEM material model 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.

Parameter Editor

The Parameter Editor allows you to modify the parameters once the deck is loaded. The parameters that you can modify are: Particle-Particle interactions, Particle-Geometry interactions, and Physics model parameters and options.

To use the Parameter Editor:

In the EDEM Cal page, select Parameter Editor and specify the following details:


For	Specify
Properties	The Properties section is populated depending on the settings in the prototype simulation deck. The interaction option will allow you to modify the parameters defined in the Interactions Properties of the Bulk Material and Equipment Material section of EDEM. Using the Contact Models section, you can modify the parameters defined in the Contact Model specified in the prototype simulation deck. EDEM Cal does not allow you to change the Contact Model specified in the prototype simulation deck. When you select a Parameter to modify, the Number of Variances column will be updated to indicate how many values will be changed.
Fields	Select a property in the Properties section to view the fields in the Fields section. Select the specific interaction to be modified or a setting in the Contact Model. For interaction-based parameters, the specific bulk material-bulk material/equipment material combination is listed. The Cases to be generated value is updated depending on the number of parameters varied. This is the number of combinations from the parameters that you have selected to modify.
Parameters	Once you have selected a Property and Field, the Parameters are updated as a reflective value of the current value in the prototype deck. There may be more than one parameter which can be changed. Selecting the appropriate parameter will allow you to vary that specific parameter. Click Add to discard the original value and use the newly defined value. You can also add multiple values in this interface. Select a value and click Remove to delete a value. By default, adding a new value will overwrite the original value and that value does not have to be removed. To include the original value in the calibration, re-add that value to be used in the calibration.

Note: All these parameters need to be varied. Any parameters that are not selected will run with the original value defined in the prototype simulation.
