Below you can find links and details about Altair® EDEM™ tutorials and scripts on Altair Community

If you are new to the Discrete Element Method, we have e-learning and online training sessions in addition to the Altair How-To YouTube series.

Introductory tutorials designed to give familiarity to the EDEM user interface, creating materials and importing CAD

  1. EDEM Conveyor example, introducing particle shapes and conveyor kinematic
  2. EDEM Screw Auger example, introducing material to rotating geometry
  3. Rock Box using Mixed Shape Solver (Polyhedral + Spheres)
  4. How to model Polyhedral Particles

Tutorials outlining the different physics models in EDEM

  1. Tavares Breakage for SAG Mill
  2. Learn how to use the Linear Elastic Bonded Model model for solids and soft soils
  3. How to use the 1-way coupling to introduce a flow field and calculate Lift and Drag forces
  4. Printer based tutorial for Electrostatics and Tribocharging
  5. How to use the Edinburgh Elasto-Plastic Adhesion model and the Hysteretic spring for Tablet Press simulations
  6. How to model conductive Heat Transfer with DEM

For Heat Transfer you can customise the physics, for example, to include geometry as a heat source.  For the 1-way coupling you can also customise the physics as shown here and here, or for coupling EDEM to AcuSolve either 1-way (Unidirectional) or 2-way including heat and mass transfer, the tutorials are here:

Tutorials for different EDEM Applications

  1. How to use the bonded particle model to generate flexible materials for cutting (e.g. mowers and grass cutting)
  2. Using Spherocylinders with bonds for flexible materials
  3. Model a transfer chute with the discrete element method and introduce cohesive materials with the JKR model
  4. How to setup a Slatted Conveyor belt in EDEM
  5. How to model Mixing in a Tablet Coater, focussing on the post-processing

Or if using EDEM BulkSim we have transfer chute and material modeler tutorials for this.

For custom EDEMpy custom analysis you can get started here:

There are lots of EDEMpy examples on Altair Community, for example:

You can also benefit from the knowledge of experienced EDEM users. We have a series of webinars presented and recorded for on-demand viewing, you can see the EDEM Webinars here:

And more presentations from ATCx Discrete Element Method 2022

Material Calibration and Advanced functionality

To start with EDEM calibration please see the e-learning materials:

Or our blog:

Tutorials can be found here:

  1. How to introduce blocks of material to a simulation with the EDEM Block Factory
  2. How to improve simulation speed by freezing particles using Dynamic Domain
  3. How to improve simulation speed by reducing the domain size using Cylindrical Periodic Boundaries
  4. How to calibrate discrete element materials, use EDEM batch and EDEMpy

Some further details on how to use EDEM Batch Mode:

For Calibration of EDEM results with Hyperstudy you can use the Hyperstudy-EDEM link:

And here Lead Engineer Stefan Pantaleev discusses Machine Learning and Optimisation for EDEM processes:
