Introduction to Efficiently Modeling Antennas in COMSOL Multiphysics®

Jiyoun Munn | October 31, 2016

To keep our antenna modeling process efficient and accurate, we should start with a simple geometry and then gradually add more complex features. The final simulation needs to include enough detail to accurately represent our design, while excluding elements that needlessly increase the computational cost. To demonstrate this, we look at an anechoic chamber example, which is used to characterize antenna performance, before examining how this process applies to several antenna examples available in the COMSOL Multiphysics® software.

Imagine bending a metallic paper clip back and forth until, after a few repetitions, it breaks entirely. This is one example of fatigue failure, the most common type of structural collapse. In more severe cases, such failure can lead to collapse or malfunction in structures like car exhaust pipes and aircraft jet engines. To better understand and predict fatigue failure in elastoplastic materials, we can use the COMSOL Multiphysics® software to accurately model both the materials and the fatigue process.

The 12th annual COMSOL Conference made a stop in Bangalore last week, where it was packed for over two days with learning and networking opportunities. Each year, the conference brings simulation experts from both industry and academia together, and this year was no different! Read on for highlights from the conference and a photo slideshow.

Aside from the winding type, concentrated or distributed, the logic behind the design of electrical machines is relatively similar, as it’s based on their phasor diagrams. Using an induction motor benchmark model with a concentrated winding, we’ll show you how to create selections in the COMSOL Multiphysics® software to streamline the analysis of your winding design. We’ll then demonstrate how to further advance your simulation studies by automating these processes with the Application Builder.

A short circuit in a battery is bad news: the chemical energy stored in the battery is lost as heat, rather than being used to power a device. Short circuits create intense heat, which can degrade battery materials or lead to fires or explosions due to thermal runaway. To avoid conditions that lead to short circuits in devices and ensure that short circuits do not cause unsafe operating conditions, we can study lithium-ion battery designs with the COMSOL Multiphysics® software.

In certain food and pharmaceutical industries, different types of dryers are used to dry heat-sensitive products. Vacuum dryers offer one solution for removing water and organic solvents from these sensitive substances. For optimal vacuum dryer design performance, engineers need to balance the dual needs of a rapid drying time and high-quality end products. To achieve this, you can study the vacuum drying process with the COMSOL Multiphysics® software.

To accurately simulate a gear and obtain useful results, it is important to consider a number of elements behind the device’s design and how they are modeled. New features and functionality in the COMSOL Multiphysics® software provide you with the tools to address such properties and thus advance the reliability of your simulation studies. Today, we’ll review the various elements of gear modeling and explain how to account for them in our modeling processes.

Developing a device that generates nuclear fusion would provide a nearly limitless amount of clean energy on Earth. But while work on thermonuclear fusion began in the 1950s, engineers are still trying to make this goal a reality. One approach has been to use magnetic confinement devices known as tokamaks. See why a group of engineers at MIT’s Plasma Science Fusion Center (PSFC) turned to simulation to address a key challenge in tokamak design: instability due to plasma disruptions.

Last week, users of COMSOL Multiphysics® presented innovative projects at the COMSOL Conference 2016 Boston. Topics ranged from the human body to acoustic black holes, and while it was hard to pick favorites, a few of the submissions stood out above the rest. Attendees voted for their favorite poster and our committee selected six of the best papers and posters. Curious about who won? Here’s a round-up of the top papers and posters from the COMSOL Conference 2016 Boston…
