Altair EDEM Software | DEM Simulation for Bulk and Granular Materials

Altair EDEM is Discrete Element Method software for simulating bulk and granular materials and how they interact with equipment under real operating conditions. It helps engineers analyze material flow, loading, wear-related behavior, and process performance across applications such as heavy equipment, mining, steelmaking, and process manufacturing.

What is Altair EDEM?

Altair EDEM is high-performance DEM software used to simulate and analyze the behavior of bulk and granular materials such as ores, soils, grains, tablets, powders, fibers, and similar particle-based media. It can be used on its own or alongside other CAE tools to study how those materials move, interact with machinery, and affect equipment performance across operating and process conditions. EDEM’s documented workflow includes Creator for model setup, Simulator for solving, and Analyst for result review and post-processing.

Key Features Of Altair EDEM

CAE Coupling for Broader Engineering Workflows

EDEM can be coupled with other CAE tools to extend particle simulation into broader engineering studies. Official Altair sources support coupling with CFD, FEA, and multi-body dynamics workflows for fluid-particle interaction, structural loading, and equipment motion studies.

EDEM Capabilities

CAD Geometry Import and Equipment Setup

EDEM Creator supports importing equipment geometry from common CAD formats including IGES, STL, and STEP, helping users build simulation environments around real equipment shapes. Geometry sections can also be imported as part of model setup.

Motion Definition for Equipment Behavior

Users can assign equipment motion in EDEM Creator, including linear, rotational, sinusoidal, force-driven, and torque-driven motion. This supports studies where bulk material behavior depends on moving machinery or process equipment.

Particle Shape Modeling

EDEM supports Multi-Sphere, Polyhedral, and Sphero-Cylinder particle shapes. Documentation also shows support for imported CAD geometry in polyhedral definitions and sphere fitting for creating complex shapes.

Material Definition and Interaction Setup

EDEM Creator includes bulk material setup and the definition of interactions between materials and geometry. The material workflow is supported by material data transfer tools and starter resources in the documentation.

Material Calibration Tools

EDEM includes EDEM Cal and EDEM Calibration Kits to support material model calibration using standard bulk solids characterization tests. The calibration kits also include Python scripts for computing and reporting standard test results.

Physics Models for Material Behavior

EDEM includes validated physics models and documented support for contact models such as Hertz-Mindlin, JKR, Edinburgh-Elasto-Plastic-Adhesion, Bonded V2, and wear models including Archard Wear and Relative Wear. This is one of the key foundations for representing a range of bulk material behaviors.

Custom Physics and API Extensibility

EDEM provides an API for implementing user-defined contact physics, particle-generation factories, and external couplings through plugins. This makes it possible to extend the software for advanced or highly specific particle behavior.

Coupling Interfaces for CFD and MBD

The EDEM Coupling Interface supports coupled simulations with generic CFD codes and rigid or multi-body dynamics codes, allowing two programs to operate synchronously and share data during a coupled simulation. Solver capability tables also confirm support for CFD and MBD coupling interfaces.

Analysis, Visualization, and Query-Based Review

EDEM Analyst provides tools to review and examine simulations, including clipping, field display, graphs, geometry bins, grid bins, and query-driven data extraction. It also supports continuum-based analysis views for interpreting particle data as a continuum.

Data Export and Downstream Use

Users can export simulation data from single time steps, time ranges, selected elements, or bin groups. Documentation also supports export paths for pressure and force data suitable for HyperMesh and SimSolid, plus geometry and particle export to CAD files and image export during simulation.

Python Access with EDEM py

EDEM py is included for accessing EDEM .h5 data files and supports both pre-processing and post-processing through the Python ecosystem. This is useful for teams that want custom analysis, automation, or reporting workflows around EDEM data.
