How to Analyze Laser Cavity Stability with Multiphysics Ray Tracing
If you’re looking for an in-depth example of multiphysics ray tracing, then check out this blog post about analyzing and predicting laser cavity stability in the COMSOL® software.

How to Model Heat and Moisture Transport in Porous Media with COMSOL®
Modeling the transport of heat and moisture in porous media, like building envelopes and other construction materials, is a simple process with a predefined Heat and Moisture Transport interface.

How Does the Choice of Ray-Tracing Algorithm Affect the Solution?
When performing a high-frequency optics simulation, do you use a sequential, nonsequential, or exact ray tracing algorithm? Learn how to choose to make the most of your solution.

Simulating Powder Compaction with Porous Plasticity Models
Powder compaction is an important and popular technique in many manufacturing industries. You can use porous plasticity models to analyze and improve the powder compaction process.

How to Model Heat and Moisture Transport in Air with COMSOL®
First, we discuss how to model heat transport in moist air. Then, we add complexity by demonstrating how to couple heat and moisture transport in air in your simulation.

Optimizing Microwave Furnaces for Solar-Grade Silicon Production
For silicon to be considered “solar grade”, it has to be 99.9999% pure. Therefore, microwave furnaces used to produce solar-grade silicon need to be optimized for quality and efficient output.

How to Calculate a Capacitance Matrix in COMSOL Multiphysics®
Calculating the capacitance between two conductors is simple, but adding more conductors to the mix (as is the case with touchscreens, transmission lines, and capacitive sensors) adds complexity.

How to Model the Optical Properties of Rough Surfaces
We develop a computational model for calculating the optical properties of rough surfaces, such as incident light on a dielectric material with random variations in height and thickness.
