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.
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.

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.

To save the Material block:

Click Save Material Block, the current simulation domain is defined as the bounding box as specified in the Creator Tree > Environment > Domain at the Time Step.

Note: Saving a Material Block automatically saves the Bulk and Equipment Materials used for it along with the corresponding interactions. All this data will be available in any other EDEM deck through the Materials database.

The Contact Model specific information is also saved. For example, if the Bonding V2 model is used, the bond contact information is stored in the Material block.

The purpose of this tool is to generate a bed of material by just assembling multiple copies of a Material block. An alternative use of the Material block is to take the output of one simulation and use it as an input to another, using the Dynamic Block Creation functionality.

In either case, in to obtain the Sample block, an initial simulation is necessary before returning to the Creator to save the Material block into the Internal Materials Database.
