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.
  - Add Bulk Material to a Model
    A Bulk Material comprises the particle bulk material properties, particle shape, and size distribution.
  - Add Bulk Material Particles
    You can add bulk material particle shapes such as Multi-Sphere, Polyhedral, and Sphero-Cylinder.
  - Create and Define Meta-Particles
    A Meta-Particle is a collection of individual Multi-Sphere or Sphero-Cylinder particles bonded together using EDEM’s Bonding V2 contact model.
  - Size Distribution for Particle Shapes
    You can specify the size distribution for the particle shapes in each Bulk Material including Meta-Particles.
  - Material Starter Packs
    The Soils Starter and Powders Starter packs are installed with EDEM.
  - Materials database
    You can store and transfer material, interaction data, Meta-Particles, and Material Block data in a database file between simulations.
    - The GEMM Database
      The GEMM database addresses one of the most difficult aspects of DEM modeling by obtaining the appropriate material inputs for a precise representation of bulk materials.
    - The Powders Database
      The EDEM Powders database is a collection of pre-calibrated EDEM material models for powders.
    - Save the Material Block
      You can store the particles inside the current simulation domain in the form of a Material Block in the Materials database.
- 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.
- 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.
EDEM Calibration Kits
The EDEM Calibration kits are a collection of EDEM models of standard bulk solids characterization tests commonly used for EDEM material model 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.

Materials database

You can store and transfer material, interaction data, Meta-Particles, and Material Block data in a database file between simulations.

To move the Materials Database (for example to a shared network folder for use by multiple clients):

By default, the Materials Database (MaterialsDB.h5) is installed at My Documents > Altair > EDEM folder.

Note: Bulk Materials also contain the Particle Shape and Size Distribution information.
Update the location information by navigating to Tools > Options > File Locations and then browsing to the new location.

Note: The Materials Database supplied with EDEM does not contain example material types.
