Appendix
This section provides additional information about how to estimate simulation time, supported EDEM File types, attribute definitions, and so on.
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.
Particle Display Options
EDEM uses a legacy method for displaying particles if you select Options. If this option is not selected, EDEM utilizes more of the graphics card on the processing machine to improve the speed of displaying particles, especially for large amounts of material (1 million + particles).

Welcome
What's New
New features and enhancements available in EDEM.
Release Notes
This document contains information about the EDEM release, such as key features and enhancements, bug fixes, and known issues.
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.
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.
  - Particle Display Options
    EDEM uses a legacy method for displaying particles if you select Options. If this option is not selected, EDEM utilizes more of the graphics card on the processing machine to improve the speed of displaying particles, especially for large amounts of material (1 million + particles).
  - Use Remote Desktop
    Remote desktop is generally installed on most Windows operating systems. The advantage of using Remote Desktop with EDEM is that you can use all the local computers programs, files, and network resources.
  - Use Turbo VNC and Tight VNC
    Virtual Network Computing(VNC) is an alternative to Remote Desktop. This comes with a client to be installed on your machine and a server to be installed on the processing machine, which can be a Windows or Linux processing machine. Generally, Administrator privileges are required for setup.
- 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.
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.

Particle Display Options

EDEM uses a legacy method for displaying particles if you select Options. If this option is not selected, EDEM utilizes more of the graphics card on the processing machine to improve the speed of displaying particles, especially for large amounts of material (1 million + particles).

Testing on a Windows processing machine with Nvidia GTX 970 graphics card shows that the frame rate with legacy particle display on Remote Desktop is around 10 fps, and the frame rate without legacy particle display on Turbo VNC is 50 fps.
Displaying particles is 15x-25x faster without legacy particle display, but the reading data speed remains unchanged. As a result, creating videos and playing through simulations (1 million particles and ½ million particle simulations tested) is 20%-30% faster on Turbo VNC, as the animation speed is a combination of reading and displaying data.
You cannot use this option by default with Remote Desktop. You must use the slower legacy display option. For more information about how to use workarounds for Turbo VNC and Remote Desktop, see Use Remote Desktop and Use Turbo VNC and Tight VNC.
