EDEM Analyst
EDEM Analyst is the post-processor used to analyze and visualize the results of 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.
HyperMesh Data
You can export pressure and force data on a specific Geometry in text format suitable for HyperMesh import during your simulation.

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.
- 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.
  - Simulation Deck
    You can export the simulation deck during your simulation. Exporting a deck allows it to be transferred to another location and run using identical simulation parameters.
  - Results Data
    You can export specific data collected during your simulation for analysis using general settings or queries.
  - Continuum Data
    You can export Continuum data during your simulation and analyze your simulation data as a Continuum instead of discrete particles. You can also analyze particle data using Continuum-based theories.
  - HyperMesh Data
    You can export pressure and force data on a specific Geometry in text format suitable for HyperMesh import during your simulation.
  - SimSolid Data
    You can export data export force data on a specific Geometry in text format suitable for SimSolid import during your simulation.
  - ANSYS Workbench Data
    You can export pressure and force data on a specific Geometry in text format suitable for ANSYS Workbench import during your simulation.
  - Data to STL
    You can export Geometries and particles to a CAD file during your simulation.
  - Breakage Particle Size Distribution
    You can export the size distribution of particles produced when using the Breakage model.
  - Images
    You can export images collected during your simulation.
- 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

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.

HyperMesh Data

You can export pressure and force data on a specific Geometry in text format suitable for HyperMesh import during your simulation.

To export HyperMesh data:

Navigate to File > Export > HyperMesh Data.

In the Export Data for HyperMesh dialog box, select Use SI base units or Use EDEM specified units, and then specify the following details:


For	Specify
Timestep Selection	Specify the Start and End Time Steps. Data can be exported for a single Time Step (where Start and End Time Steps are equal or ‘Time Step per file’ is selected) or as time-averaged values (where the Start and the End Time Steps differ and ‘Average to file’ is selected) to minimize the effects of spiking.
Force and Pressure Export
Geometry	Select the Geometry for which data is to be exported.
Element Pressure	Select the checkbox and specify the element pressure to export the pressure data per Geometry mesh element.
Element Force	Select the checkbox and specify the element force to export the pressure data per Geometry mesh element.
Contact Force	Select the checkbox and specify the contact force to export the contact force data per Particle-Geometry contact point.
Orient and transpose to initial CAD position	Select the checkbox to allow transient analysis to be performed in HyperMesh without the Geometry moving from its initial position. For each Time Step, the force and pressure data is mapped to the initial position.
Material Center of Mass Export	Select the checkbox to specify a pre-defined particle (manual selection) in order to export the X, Y, and Z co-ordinates of the Center of Mass and total mass for the selection.

Click Export to write the .csv file containing the load data for importing into HyperMesh and the file containing the information about the particle manual selection.
