Usage/Installation Instructions

This simulation uses a bonding contact model to demonstrate particle bonding. A wedge cuts through a box of particles that are loosely bonded together.

The model is using the index method to modify a custom property. Using the index method provides performance improvement. The torque calculation for the rolling friction has also been updated to comply with the changes introduced in API version 2.4.
