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.
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.

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.

Python scripts for automatically computing and reporting the standard test results are also included in each kit. The kits are located in the EDEM installation folder under examples. The workflow consists of copying the simulation decks, modifying the material model properties in EDEM, running the decks and triggering the Python script for post processing. Multiple decks can be post-processed at once if they are located in the same folder tree. For more information about using the calibration kits, see the usage documentation for each kit.
