Overview:
Attached to this post you will find the source code and the compiled dll/so file for the calculation of some of the most common collision metrics. These metrics include the collision energy loss, duration and relative velocity. You can learn more about how the energy loss is calculated in this post.
Prerequisite:
EDEM 2025.0 or newer versions
Usage/Installation Instructions:
To use the API, place the dll/so (Windows/Linux) file in the same folder as your .dem file. If you want to run the simulation using the GPU, you also have to place the .cu file in that same folder.
While in the Creator, go to the Physics section and add the model as a particle-particle or particle-geometry contact model. Once the model is added, click on the wheel icon and then you can choose which metrics you want to track, and you can set the parameters used to create the histograms. If the model is added as both particle-particle and particle-geometry, the parameters in both GUIs must be the same.
Post-Requisite:
Release Version:
EDEM 2025.0
