What’s New in EDEM 2023

Combining multi-sphere, polyhedral and sphero-cylindrical particles
One of the main additions in this release is that it is now possible to add Sphero-cylinder, Multi-Sphere and Polyhedral particles to the same simulation.
Since the addition of polyhedral and sphero-cylinder particle shapes to EDEM, users have been requesting to combine all shapes in the same simulation to further enhance their results.
Now, any particle shape currently supported can be combined in a single simulation with any other particle shape, providing users with deeper insight and analysis for all industry applications. This offers users the ultimate flexibility with mixed particle shape simulations where users can mix and match particles like never before!
In addition, the mixed particle shapes are supported for the materials database, meta-particle, volume packing, material block functions, and particle attributes has now standardized outputs, such us diameter and length.
High Performance Bond Model for all Particle Shapes
A new bond model has been added - the Linear Elastic Bonding Model (LEBM). Previously, users has been restricted to the traditional Bonding V2 model designed for spherical particles.
With the addition of polyhedral and sphero-cylinder particle shapes, an alternative model was required to cater for more complex scenarios for specific types of applications.
This new model forms elastic bonds between particles that can be broken under tensile or shear forces, allowing better performance and removing the need of a base model, like Hertz-Mindlin.
New Residence Time Analysis
New residence time analysis for defined regions is now available to allow users to track the time a particle has spent in a region.
Some applications require this type of analysis in a specific region in the equipment, while the current residence time (EDEM 2022.3 and lower) only allows users to consider the full domain.
The new analysis also uses different container shapes like spherical or cuboids and offers more insights into particle behavior and particle tracking with better precision.
New Fully Integrated API GUI for Custom Models
EDEM’s API has been revolutionized with the ability to create user-friendly interfaces for custom models, eliminating the use of old text-based preference files.
Using the old text-based preference files, the values entered were not saved in the simulation files. Now, the models are fully integrated and behave like a built-in model without losing data and performance.
Users also benefit from a more user-friendly interface that also allows more complex physics for the contact model API. All API models can now easily be configured and maintained by customizing them as required at any time using tabulated parameters.
What else?
EDEM 2023 includes several other additions and improvements in the GUI and performance increase in the solver for multi-sphere and polyhedral shapes.
EDEMpy has also been updated to include new capabilities, like volume packing, particle size distribution setup or parallel processing.
