This simulation uses a bonding contact model to demonstrate particle bonding. A wedge cuts through a box of particles that are loosely bonded together.
Please take a look at the code for your own project and remember to come back and post up any modifications or code snippets which will help other users along the way. Feel free to use this forum for asking questions about this contact model.
