EDEM API: Voidage V2: A Voidage calculation model
Altair EmployeeOverview
In EDEM 2017.2 and earlier, the Voidage can be obtained by creating a Grid Bin and creating a Voidage query. The EDEM Voidage however does not consider the overlap between particles, which quantifies the deformation of the particles, since it is calculated based on the volume of particles only.

Usage/Installation Instructions
The Voidage V2 API model considers the overlap between particle in the voidage. The Voidage V2 API model uses the API contact and Particle Body Force plugins, and works as explained in the attached “Voidage V2 API model” PDF file.
The Voidage V2 API model does not add any forces, and therefore can be used as a plugin with any other contact model / particle body force model.
Here you will find the UDL source code and the documentation for the Voidage V2 API model:
- Voidage_V2.zip: contains the source code for the Voidage V2 API model, a simulation deck example, the compiled .dll application and the Prefs_file.txt.
- Voidage V2 API model.pdf: a small but complete guide explaining the calculation of the Voidage V2, how to use the API model to calculate the Voidage, but also recommendation as of when to use this model, and some limitations of the model.
