Overview of the User’s Guide
The Ray Optics Module User’s Guide gets you started with modeling 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.
Ray Optics Modeling
The Ray Optics Modeling chapter provides an overview of ray tracing simulation. It begins with an overview of the Essentials of Ray Tracing. It then describes the major functionality groups that are included in The Geometrical Optics Interface, including topics such as Geometry and Meshing, Ray Release Features, Study Types, and Results Analysis and Visualization.
Ray Optics Interfaces
The Ray Optics Interfaces chapter describes The Geometrical Optics Interface and includes the Theory for the Geometrical Optics Interface.
Multiphysics Interfaces and Couplings
The Multiphysics Interfaces and Couplings chapter describes The Ray Heating Interface, a dedicated multiphysics interface for computing heat sources generated by attenuation of rays in absorbing media, and includes the Theory for the Ray Heating Interface.
