This tutorial describes how to create a Geometry Custom Property, based on an existing contact model supplied with EDEM. The Hertz-Mindlin model is modified to include the calculation of the pressure from the particle forces acting on the equipment.

The main focus is on:

• Use of Visual Studio to create and compile an EDEM API model
• Modification of an API model to introduce Custom Properties
• Modification of physics to include Pressure calculations
• Using the configForTimeStep function
• Updating the source code to run on GPU
