Get a comprehensive background on probability distribution functions and the different ways you can sample random numbers from them in COMSOL Multiphysics®. Part 1 of a series on beam physics.

How to Model Solar Concentrators with the Ray Optics Module

June 23, 2016

Learn how to predict the concentration ratio for an idealized, parabolic solar reflector using Monte Carlo ray tracing in the Ray Optics Module, an add-on to COMSOL Multiphysics®.

Using the New Ray Tracing Algorithm in COMSOL Multiphysics® 5.2a

June 20, 2016

The ability to trace rays in unmeshed domains, and even release and trace rays outside a geometry, has been available in the Ray Optics Module as of COMSOL Multiphysics® version 5.2a. Learn more.

Evaluating Static Mixer Performance with a Simulation App

June 8, 2016

In this blog post, we go over the setup of an app designed to quantitatively and qualitatively analyze the performance of a static mixer using the Particle Tracing Module.

Modeling Thin Dielectric Films in Optics

May 6, 2015

Interested in modeling optical systems with dielectric films? Get an overview of some of the built-in tools in the Ray Optics Module for these modeling scenarios.

Ray Tracing in Monochromators and Spectrometers

December 25, 2014

Spectrometers are optical devices that measure some property of radiation as a function of its frequency, while monochromators transmit radiation of a specific frequency.
