Modeling Heat Transfer in Thin Layers via Layered Material Technology

April 1, 2019

We answer some questions you may have about the Layered Material functionality in the COMSOL® software: What does it do? How do you update existing models? How do simulations benefit from it?

RF Module Part Library: An Easier Way to Model RF Devices

March 28, 2019

Sometimes, your models need to include connectors. Instead of spending time creating geometries for each connector, you can simply add them from the Part Library.

Performing a Multiphysics Analysis of a Thermal Microactuator

March 8, 2019

To design an optimized thermal microactuator for use in a specific device, you need to account for tightly coupled electrical, thermal, and structural phenomena in your analysis.

Reducing the Magnetic Signature of a Submarine

March 7, 2019

For a submarine to avoid detection and remain “under the radar”, engineers need to investigate the magnetic signature of the vessel’s design. Electromagnetics simulation is up to the task.

How Eddy Current Braking Technology Is Freeing Us from Friction

March 6, 2019

What moves must eventually stop. Unlike mechanical brakes, eddy current braking systems prevent damage when braking at high speeds. Hop on and learn more about eddy currents in this blog post.

Efficiently Analyze Charge Exchange Cell Designs Using Applications

March 5, 2019

Due to their neutral ion beam, charge exchange cells are used in processes ranging from ion implantation and semiconductor fabrication to synchrotron devices and medical research.

Hydrodynamic Thermal Transport in the Kinetic-Collective Model

February 28, 2019

F. Xavier Alvarez from the Universitat Autònoma de Barcelona (UAB) discusses using COMSOL Multiphysics® to model heat transfer at the nanoscale and better understand transport processes.

Studying the Polarization of Light with a Fresnel Rhomb Simulation

February 27, 2019

A Fresnel rhomb is a simple optical system for studying light polarization. Follow along as we simulate linearly, elliptically, and circularly polarized incident light in a Fresnel rhomb.
