EDEM Software Platform diagram showing components and extended capability

EDEM Creator



EDEM Creator is the pre-processor for setting up an EDEM simulation model. Within the EDEM Creator users:

  • Import their equipment CAD models
  • Characterize the bulk materials being simulated
  • Design representative models of particles for use in the simulation model
  • Choose the physics that are best suited to model the behavior of the real materials

EDEM Creator allows the user to setup simulations in a fast, logical manner. Users construct a DEM model of their material comprising the model particle shapes, the particle-scale physics models and parameter values. This is followed by defining the size distribution and initial conditions of the model particles that will be introduced to the simulation as it progresses.

To replicate their actual equipment, users can import a wide range of CAD files or even create simple equipment geometries within EDEM. EDEM supports a wide range of measurement units based on both SI and Imperial systems. There are no restrictions to the mixing of units and it is possible to switch between units at any time during the specification of a simulation.

Global Simulation Properties

Within EDEM Creator users can specify a number of global properties to model their granular solids system. From the selection of contact physics models and gravitational effects to the definition of material properties, the user can specify their choices in a series of clear, easy to use menus and input boxes.

Creator User Interface features easy to use controls and full, interactive 3D visualization


The default contact model for each EDEM simulation is the Hertz-Mindlin (no slip) model with additional models available for adding RVD friction, JKR cohesion, bonding or heat conduction. As an alternative to the Hertz-Mindlin model, additional models for linear spring, linear cohesion, hysteretic spring and electromagnetic tribocharging are selectable.

Newly created materials and material interactions assigned to particles or equipment geometries can be saved, exported and imported from the EDEM materials database. The feature allows users to reuse and share common materials between their EDEM simulations.


Representative Model Particles

EDEM Creator provides the tools to create representative particle shapes of the materials to be simulated. Users can add the mechanical, material and other physical properties to calibrate and customize their model particles. These can be stored in a library, enabling users to compile a collection specific to their processes.

Multi-spherical particles can be used to model real world material shapes.
Extra realism can be added by using CAD templates to represent the material


EDEM simulation technology is based on the highly versatile multi-sphere method for representing non-spherical particles. Users can create complex multi-element particles from simple spherical elements. CAD templates of real particles can be imported to provide realistic particle visualizations as well as automated calculation of the particle parameters, such as moments of inertia and mass, from either the multi-sphere model or template. EDEM provides the ability to import and export particle models to allow common models to be shared between EDEM simulations.


Equipment Geometry

EDEM Creator’s class-leading CAD import capability makes it easy for users to import their existing or prototype machinery or equipment designs into the simulation domain. This provides a virtual prototype for reproducing observed particle flow behaviour and simulating interactions between the bulk solids and the equipment.

When required, EDEM also provides the easy creation of basic geometries, such as cubes, cylinders and surfaces. Users can also reproduce equipment movement by assigning linear or sinusoidal translations and rotations to individual geometry sections as well as conveyor dynamics.


File formats that are supported for import into EDEM:
File Extension Source Software Application

In addition to CAD import EDEM easily creates simple geometries


EDEM Particle Factory® Technology

The EDEM Particle Factory® tool provides a powerful, straightforward method for users to input the bulk material into their simulations. Users can choose to generate a continuous flow of granular material for a specified duration or create them instantaneously to a fill a container. Therefore a variety of scenarios, such as particles falling under a gravity field or flowing horizontally into the simulation domain, exiting a piece of equipment or sitting in a container, can all be created.

Create Particle Factories™ quickly, using planar or volume geometries to define the zone of particle generation


The EDEM Particle FactoryTM easily allows the specification of a range of initialization conditions including linear and angular velocity, size and orientation. Particles can also be scaled to provide a range of sizes. Size distributions options include linear, normal, and log-normal distributions. Particle placement can be random or can use a lattice formation (cubic, FCC or BCC).

Generation rates can be set with a target of either mass or number of particles. This lets users control the total flow to replicate on site conditions and evaluate equipment performance.
