Does anyone have the API for the Linear Elastic Bonding Model?

"Does anyone have the API for the Linear Elastic Bonding Model? The corresponding tangential stiffness ktkt​ in EDEM's built-in model changes based on the particles' Poisson's ratio, and I would like to set it myself instead of modifying the particles' Poisson's ratio."

thanks

Hi,

We don't share the API for the LEBM model due to confidentiality/IP. You could consider writing the model based on the reference:

Linear Elastic Bonding Model

C. A. Labra (2012) Advances in the development of the discrete element method for excavation processes. Universitat Politècnica de Catalunya.

J. Rojek, C. Labra, O. Su, E. Oñate (2012) Comparative study of different discrete element models and evaluation of equivalent micromechanical parameters. International Journal of Solids and Structures 49, p.1497-1517.

The EDEM product team is working on API updates which will allow us to share some components of the models while keeping others confidential, that has not been implemented in the 2025 version but is planned for future releases.

Regards

Stephen
