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.
Creator Tree-Geometries
Creator Tree-Geometries allows you to use Geometry sections to construct the environment in which your bulk material interacts.
Geometry Motions
Sections of a Geometry can be static or dynamic. Static sections remain in a fixed position during the course of a simulation whereas dynamic sections move. Sections can move under fixed translation, rotation, conveyor motion, or sinusoidal motion.
Parent-Child Functionality
You can define Geometry sections as 'children' of another Geometry section owing to Geometry handling in EDEM.

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.
- Creator Tree-Project
  Creator Tree-Project allows you to define the title and description for the simulation.
- Creator Tree-Bulk Material
  Creator Tree-Bulk Material allows you to add bulk material and bulk material particle shapes to a model and define their interactions.
- Creator Tree-Equipment Material
  Creator Tree-Equipment Material allows you to add equipment material to a model and define interactions between materials.
- Creator Tree-Geometries
  Creator Tree-Geometries allows you to use Geometry sections to construct the environment in which your bulk material interacts.
  - Select Geometry Sections
    You can select Geometry sections by clicking the required Geometry in the Viewer window. The Geometry in the Creator Tree is highlighted.
  - Create a New Geometry Section
    You can create sections in EDEM or import them from a CAD program to create particle factories.
  - Import Geometry Sections
    Instead of defining Geometry using EDEM, you can import Geometries from a variety of CAD applications.
  - Work with Geometry Sections
    You can replace, copy, and merge Geometry sections. You can also create Geometry groups.
  - Geometry Motions
    Sections of a Geometry can be static or dynamic. Static sections remain in a fixed position during the course of a simulation whereas dynamic sections move. Sections can move under fixed translation, rotation, conveyor motion, or sinusoidal motion.
    - Kinematics
      When you use kinematics to define the equipment, they will not move when a force provided by another element is applied.
    - Motion Controllers
      Unlike kinematics, you can add motion controllers to the geometry elements to allow objects to react to Particle-Geometry forces.
    - Conveyors
      Conveyor motions are used to model systems containing conveyor belts. The Geometries themselves do not physically move as a result of this motion, but the particles in contact with them are moved based on the defined settings in this motion.
    - Parent-Child Functionality
      You can define Geometry sections as 'children' of another Geometry section owing to Geometry handling in EDEM.
  - Factories
    You can use Particle factories to define where, when, and how Particles/Meta-Particles appear in a simulation. The following types of particle factories are available - Static, Dynamic, Block, Volume Packing, and Recorded.
- Creator Tree-Environment
  Creator Tree-Environment allows you to define global settings for the simulation in the Environment section.
- Creator Tree-Physics
  Creator Tree-Physics allows you to add Physics interactions.
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 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.

Parent-Child Functionality

You can define Geometry sections as 'children' of another Geometry section owing to Geometry handling in EDEM.

This allows the 'child' Geometry to inherit kinematics from the 'parent' Geometry, reducing the amount of kinematics required in complicated systems. The key benefit of this update at this moment is the ability to create the Dynamic Domain as a child of another Geometry section without the need for movement to be controlled by an external 3rd party, such as MBD software.

Once you have defined the hierarchy in the tree, it can be identified by the indent relative to the parent Geometry as follows:

The child will now move with the parent if the parent is assigned a motion or is moved within global space (rotated or translated).

You must assign the child and select the Include Rotation From Parent Transform checkbox (found under the child's Transform) before you can set the parent Geometry's initial position. When this checkbox is selected or cleared, any unintentional movements will be minimized.

Parent Partial Transform

There is an option within the Child's Transform to exclude the rotational component of the parent's motion in order to only include a portion of the parent transform.

Navigate to Geometry > Parent Geometry > Child Geometry > Child Geometry > Transform > Partial Parent Transform. Optionally, do not select this option if you want to retain only the parent translational motions.
