This tutorial describes how to create a new cohesion contact model, based on an existing contact model supplied with EDEM. The cohesion model is modified to include time-dependent particle-to-particle and particle-to-geometry cohesion.

The main focus is on:

• Editing the physics of the Linear Cohesion model (V2) on both CPU and GPU
• Compiling and loading a Custom Contact Model
• Post-Processing the model to investigate variable cohesion
