Overview of the User’s Guide
The Granular Flow Module User’s Guide gets you started with modeling granular flow using COMSOL Multiphysics. The information in this guide is specific to this module. Instructions how to use COMSOL in general are included with the COMSOL Multiphysics Reference Manual.
As detailed in the section Where Do I Access the Documentation and Application Libraries? this information can also be searched from the COMSOL Multiphysics software Help menu.
 
The Modeling Granular Flow chapter provides an overview of the physics interface and features available for modeling granular flow.
The Granular Flow Interface
The Granular Flow Interface chapter describes the Granular Flow interface found under the Fluid Flow branch () when adding a physics interface. It also includes some theory for granular flow.
