Modeling Convective Cooling of Electrical Devices
We developed a model that includes all of the important details of thermal management in a high-power electrical device. To do so, we needed to use high performance computing with hybrid modeling.

Powering Particle Physics Research at Fermilab
Researchers at Fermilab had an important question: Would upgrading the booster RF cavities in their particle accelerator cause them to overheat? To find answers, they turned to simulation…

Computing Voltages Produced by Electromagnetic Induction
Have you ever used a “shaker flashlight”? It’s powered by voltage from the electromagnetic induction that occurs when a powerful permanent magnet inside the device oscillates due to the shaking.

Video Tutorial: Capacitive Pressure Sensor
Looking for a visual explanation of how to model a miniaturized 3D electromechanics problem? Read this blog post for a quick overview and an embedded tutorial video.

POWER Prevents Corona Discharge in Power Lines
POWER Engineers, a global engineering consulting firm, used multiphysics simulation to study if and where corona discharge occurs in power lines and their associated assemblies.

Quick Intro to Modeling RF and Microwave Heating
If you’ve attended a COMSOL webinar about an RF topic, you’ve probably seen our model of a waveguide with a bend. That’s because it illustrates microwave heating in an easy-to-understand way.

Simulating the Focusing Effect of Magnetic Quadrupoles
What’s a magnetic quadrupole lens? How do they work? How do you simulate their focusing effect? We answer these questions and more in this blog post…

Powerful Packaging for Electronics in Extreme Environments
U.S.-based Arkansas Power Electronics International is designing power packaging for improved thermal management in power electronics devices, increased efficiency, and lower costs.
