Modeling an RF Anechoic Chamber Using Periodic Structures
There are two types of anechoic chambers — acoustic and radio frequency (RF). Here, we explore how periodic structures can be used to help quickly model an RF anechoic chamber by reducing the complexity and computation time of the model.
COMSOL News 2014 Is Now Available
We’re excited to announce that COMSOL News 2014 is now available, which features stories about the cutting-edge research of engineers and scientists working in a variety of application areas around the globe. This year’s edition of the magazine provides insight into how multiphysics simulation can empower product development and help companies to stay ahead of — and create — new market trends. How is this achieved? Check out the magazine to learn more about innovative simulation techniques.
New Book on Topology Optimization for Electromagnetics
There’s a new book out there for those of you who work with or research electromechanical system design. It’s titled Multiphysics Simulation: Electromechanical System Applications and Optimization and is more than your average textbook. This is a reference guide on simulation and topology optimization written with both students and industry engineers in mind.
Vacuum Tube Plus MOSFET Equals Vacuum Transistor
IEEE Spectrum recently sent out a “Tech Alert” that included an article about vacuum transistors, which combine vacuum tubes and metal oxide semiconductor field-effect transistors (MOSFETs). The article suggests that this technology may wind up replacing traditional silicon transistors.
Converting the High Flux Isotope Reactor to LEU Fuel
Under an initiative by the National Nuclear Security Administration (NNSA), nuclear research reactors currently using highly enriched uranium (HEU) fuel must be converted to low enriched uranium (LEU) fuel with a goal to help prevent the spread of material that can be used to create nuclear weapons. Nuclear engineers at Oak Ridge National Laboratory have turned to multiphysics simulation in order to precisely and accurately explore new designs for the safe conversion of the ORNL High Flux Isotope Reactor.
Automatically Handling Selections in COMSOL Multiphysics®
This is Part 3 of a blog series on how to handle selections and entity numbers when using LiveLink™ for MATLAB® and the COMSOL® Application Programming Interface (API). In this section, I’ll discuss how the internal handling of selections and entity numbers in COMSOL Multiphysics® simulation software is performed and how you can utilize these methods when setting up your own models.
How to Join Solutions in COMSOL Multiphysics
In engineering analysis, the need to compare solutions obtained under different circumstances frequently arises. Some possible scenarios include comparing the effect of different load or parameter configurations, and enveloping results to find the worst or best case at each point of the domain. In each of these and other similar cases, you need access to more than one data set. Here’s how to accomplish such tasks using COMSOL Multiphysics.
FIRST® Robotics at PTC® Live Global 2014
A couple of weeks ago, we exhibited at PTC® Live Global. In addition to manning the exhibition booth and learning about PTC® Creo® Parametric™ 3.0, we were introduced to a fantastic program called FIRST®, which gets kids involved in science and technology.
