The Graphics Window: Effective and Beautiful Postprocessing

March 19, 2014

Using the Graphics window in COMSOL Multiphysics can be a little tricky if you’re not too familiar with what it can do. But once you know the shortcuts, controlling the camera and view angles to create good graphics becomes quite straightforward. I hope the techniques shown here will help you produce graphics to visualize and present your work more easily.

Benchmark Model Results Agree with Fresnel Equations

March 12, 2014

Have you ever wondered why boaters wear polarized sunglasses? It’s because sunlight reflecting off the water is primarily polarized in one direction, and polarized sunglasses will block this component of the reflected light, thus reducing glare. To understand why this is, we can use COMSOL software. This example solves the governing Maxwell’s equations using the RF Module or Wave Optics Module to simulate light incident at an angle upon a dielectric medium, and the solution shows agreement with analytic solutions.

Simulating Thermal Performance in Windows

February 4, 2014

Keeping the inside of a building at a comfortable temperature requires well designed windows to keep heat out during the summer and heat in during the winter. Let’s take a look at how windows provide thermal insulation and how they carry heat (or not) between the inside of a building and the outdoors.

Simulating an RF MEMS Switch

January 7, 2014

An RF MEMS switch is an electromechanical component found in RF systems. It usually consists of a micromechanical bridge or cantilever, a substrate, and an electrode or dielectric layer. These devices can switch at RF frequencies and tend to have high isolation, i.e. power loss when the switch turns off; low insertion loss (loss of signal power when the switch is on), and extremely low (almost zero!) power consumption. Let’s take a look at how you can use COMSOL Multiphysics […]

Predicting Microwave Drying of Potatoes

December 17, 2013

You may not think of reheating food in the microwave as a drying process, but as we saw at the COMSOL Conference 2013 Boston, microwave technology — the same technology used in domestic microwave ovens — can be used for drying fruits and vegetables. One poster presented at the conference featured microwave drying of potatoes and how the heat and mass transfer that occurs can be modeled to predict the drying process.
