EDEM Analyst
EDEM Analyst is the post-processor used to analyze and visualize the results of your simulation.
Analyst Tree-Display
Analyst Tree-Display allows you to configure the display of your model in the Viewer. You can visualize Cylindrical Periodic Boundary conditions from the Geometries section.
Display the Selections Sub-section
The Selections sub-section shows the Geometry and Particle Selections. By default, selections are not available unless you have configured them using Setup Selections.
Analyze Meta-Particles
You can analyze Meta-Particles to understand certain associated attributes. The analysis considers a Meta-Particle based on its current state in the simulation. Once a Meta-Particle breaks, it forms two Meta-Particles. For this analysis, all single particles are considered Meta-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.
- Analyst Tree-Display
  Analyst Tree-Display allows you to configure the display of your model in the Viewer. You can visualize Cylindrical Periodic Boundary conditions from the Geometries section.
  - Display the Geometries Sub-section
    The Geometries subsection allows you to modify and configure the display settings for all the Geometries in the simulation alternatively. You can visualize Cylindrical Periodic Boundary conditions in the Geometries subsection.
  - Display the Particles Sub-section
    The Particles sub-section allows you to modify and configure the display settings for all the Particles and Particle Types in the simulation. You can expand this section to select individual particle types.
  - Display the Selections Sub-section
    The Selections sub-section shows the Geometry and Particle Selections. By default, selections are not available unless you have configured them using Setup Selections.
    - Analyze Meta-Particles
      You can analyze Meta-Particles to understand certain associated attributes. The analysis considers a Meta-Particle based on its current state in the simulation. Once a Meta-Particle breaks, it forms two Meta-Particles. For this analysis, all single particles are considered Meta-Particles.
  - Display the Contact Sub-section
    The Contact sub-section allows you to independently examine the contacts between different types of particles and between particles and individual sections of Geometry. Y Particles can contact with other particle or equipment types.
- Analyst Tree-Setup Selections
  Analyst Tree-Selections allows you to extract data from a particular area or element in the domain.
- Analyst Tree-Tools
  Analyst Tree-Tools comprises the Ruler, Protractor, and Domain Grid.
- Analyst Tree-Clipping
  Analyst Tree-Clipping allows you to remove or clip areas of the model that are currently not of interest.
- Analyst Tree-Field
  Analyst Tree-Field allows you to define the way fields are displayed.
- Review Your Simulation
  EDEM Analyst allows you to review and examine your simulation.
- Export Data
  You can export the data collected during your simulation for analysis using queries. Data can be exported from a single Time Step, a range of Time Steps, from all elements in your model, or from a selection or bin group.
- Continuum Analysis
  Continuum Analysis allows you to view and analyze your simulation data as a Continuum instead of discrete particles.
- Perform Spray Coating Analysis
  The EDEM spray coating post-processing tools use a ray tracing approach that offer key advantages over the legacy Spray Coating model.
- Graphs
  EDEM Analyst allows you to plot the data collected during your simulation using a number of charts.
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 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.

Analyze Meta-Particles

You can analyze Meta-Particles to understand certain associated attributes. The analysis considers a Meta-Particle based on its current state in the simulation. Once a Meta-Particle breaks, it forms two Meta-Particles. For this analysis, all single particles are considered Meta-Particles.

You can perform analysis on Meta-Particles based on the following attributes:

Length (bounding box, extent or distance based)
Mass
Number of Particles
Volume
Position
Number of Elements

Bounding Box Method

The Bounding Box method creates a bounding box around the Meta-Particle and then calculates the diagonal for that box.

Length Extent

The Length Extent-based method adds the length or diameter of each element in the system, especially for long, continuous Meta-Particles. This method assumes that sphero-cylinders are bonded end-to-end.

Length Distance-based

The Length-based approach takes the two further-apart particles and calculates the distance between those two particles.

Known Issues

Selections are not supported for Meta-Particle Analysis.
All elements in the simulation are analyzed, irrespective of whether they are a part of the Meta-Particle or not.
