Material calibration is essential to link real world material behaviors with the virtual material to give confidence to engineers that their simulations are representative. This webinar will explain the importance of calibration and describe a material model calibration method that can be used by engineers in different industry areas. Additional support tools available to EDEM users will also be presented, including the GEMM database, starter packs and EDEM Cal.

Date: Thursday 14th May, 2020 - 10am EDT / 4pm CEST

Presenter: Dr David Curry, EDEM Principal Engineer

Duration: 45 minutes


  • What is an EDEM Material Model?
  • Why do we need to calibrate?
  • Recommend calibration methodology
  • Choosing suitable calibration experiments
  • EDEM Calibration Tools available to support users

Modelling fine particulate solids such as powders and soils with the classical micro-mechanical formulation of DEM is challenging due to the large number of particles involved. In this webinar, we will introduce the meso-scopic modelling approach which can capture the complex behavior of fine particulate solids, while utilizing a numerical particle size of an intermediate scale between the physical particle scale and the scale of the system of interest. A meso-scopic contact model will be introduced and examples of experimentally validated results from bench scale physical tests will be given along with examples of EDEM models for large scale systems.

Date: Tuesday 19th May, 2020 - 10am EDT / 4pm CEST

Presenter: Stefan Pantaleev, EDEM Engineer

Duration: 30 minutes


  • Meso-scopic modelling of particulate solids
  • EEPA contact model overview
  • Validation examples
  • Applications: hopper discharge, wet mixing, dosing

When designing heavy and off-road equipment, being able to accurately predict the loads and forces acting on equipment and understanding how vehicles interact on different terrains is key to optimizing performance. This webinar will explain how this can be achieved by coupling EDEM with Multi-body dynamics tools such as Altair MotionSolve, and will show how this solution enables engineers to perform extensive “what-if” design analysis early in the design cycle and to reduce costs associated with physical prototyping.

EDEM is the market-leading software for bulk material simulation.

Powered by state-of-the-art Discrete Element Modeling (DEM) technology, EDEM quickly and accurately simulates and analyzes the behavior of bulk materials such as coal, mined ores, soil, tablet, and powders.

EDEM simulation provides engineers with crucial insight into how bulk materials will interact with their equipment during a range of operation and process conditions.

Since November 2019, EDEM has been part of Altair.
