About EDEM
EDEM is a high-performance simulation software for bulk and granular materials.
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.

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

Set GPU CUDA Simulator Parameters

The EDEM GPU CUDA solver engine will automatically allocate the required memory and resources as the simulation runs.

To set GPU CUDA Simulator Parameters:

To review the memory settings in the EDEM GPU CUDA solver engine, go to Simulator > Tools > GPU Memory Calculator.

Note: This might be useful in situations where the simulation is getting close to the limit of memory available and you can see the estimated memory usage. In addition, when you select the GPU CUDA solver engine in EDEM Simulator, the Display GPU Memory option can be selected which will display the memory usage in the EDEM visualizer.
