Learning with Technology: 3D Printing in the Classroom
Over the years, the size and cost of 3D printers have decreased, offering new uses for this growing technology. In response to this development, more and more teachers have begun to utilize these devices within their classrooms, helping students learn in a hands-on way.
Blue LEDs Recognized with 2014 Nobel Prize in Physics
Since 1901, the Royal Swedish Academy of Sciences has recognized significant contributions to the field of physics with a Nobel Prize award. This year’s Nobel Prize in physics was presented to a team of scientists from Japan and the U.S., recognizing their work in developing blue light emitting diodes (LEDs). Let’s take a closer look at the innovative research behind this lighting technology.
Accounting for Heat in the Design of Lithium-Ion Batteries
In the performance of lithium-ion batteries, thermal management is an important element to consider. Through modeling and simulation, you can improve the design process by analyzing how heat is transferred within the energy source.
RFID Tag Read Range and Antenna Optimization
Today, guest blogger and Certified Consultant Mark Yeoman of Continuum Blue shares a numerical modeling example for RFID applications. We’ll look at how we can make use of COMSOL Multiphysics® simulation software to determine the operating read range of a passive RFID tag powered by a reader’s interrogating field. Additionally, we will look at how we can maximize this operating range by optimizing the tag’s antenna design.
Understanding Parallel Computing
People are always asking how the performance of COMSOL Multiphysics® simulation software will improve on a parallel system, especially now that large multi-core desktop computers are relatively inexpensive and it’s easy to rent time on cloud services like the Amazon Elastic Compute Cloud™. It turns out, though, that it’s not always possible to get faster performance just by throwing more hardware at the problem. To understand why, let’s take a conceptual look at computers and the algorithms COMSOL® software uses.
Photos from the COMSOL Conference 2014 Cambridge
The first stop of the COMSOL Conference 2014 has now come and gone. The event brought together over 320 simulation practitioners from the worldwide multiphysics community to the unique setting of Churchill College in Cambridge, U.K. I would like to thank everyone who made the trip and to share with you some photos from the conference.
Keynotes from the COMSOL Conference 2014 Cambridge
The COMSOL Conference 2014 kicked off with its first stop last month in Cambridge, U.K. Among other things, attendees were treated to three keynote speeches from prominent COMSOL Multiphysics® software users: Whirlpool R&D, Bang & Olufsen, and Xaar.
Piezoelectric Materials: Understanding the Standards
Standards form an integral part of the work we do as engineers, providing a common language for communicating complex information. But standards committees are not omnipotent and sometimes revised standards are not universally adopted. This has happened in the case of the standards for piezoelectric materials, particularly for quartz. This blog post explains the multiple standards used to describe piezoelectrics in literature. Although the particular focus of this post is on quartz, the standards described apply for any piezoelectric material.
