Now There’s Thermal Cloaking

Phil Kinnane March 27, 2012

As an avid reader of the physorg.com blog, I was pleasantly surprised to see a figure show up that could only have been made with COMSOL Multiphysics. Reading the article on thermal cloaking, I understood why.

A second user story for the next COMSOL News is also reaching completion with exciting results (read about the first one here). This is an interesting case as it wasn’t really a group of people traditionally associated with finite element that managed to perform some pretty sophisticated modeling. In fact two of them are medical doctors while the final one has his background in physics.

Following up on my previous blog post about protecting wind turbines from lightning strikes, I got to thinking about other modeling aspects of wind turbines. Structural mechanics is of course important, and we have a couple of models that center on this.

Many devices live with a dry, technical name that either basically says what the device does, or is an acronym of that dry, technical name. Very few get a nickname that sticks to become the industry standard.

Reading physorg.com, I came across this story about miniaturizing antennas for smaller wireless devices. Apparently, the size of the antenna often limits the size of the wireless device – so let’s make those antennas smaller. The article is about a group from the University of Michigan who achieves this by using a hemispherical substrate with a spiraling antenna taking advantage of the volume that the hemisphere provides.

Gecko lizards use dry adhesion forces to climb vertical and even backward-slanting walls. Yet, despite the strength they provide for holding their body to such walls, you can easily pluck them from their surface, and no residue is left behind. Imagine doing that with a TV.

One of the things I have noticed from the FEM vs FVM debate is that when you want to couple other physics to fluid flow, then FEM is the best method to do this with. It’s fitting then that my colleague in our Palo Alto office, John Dunec, ran a webinar this week on Multiphysics Flow Simulations with COMSOL.

I have just read a cool article about the University of Michigan’s solar car. Back when I was a young and hopeful engineering student in Australia , the World Solar Challenge really sparked my imagination. This is the race from the top of Australia (Darwin) to the bottom (Adelaide) across the desert where the cars are powered by solar energy, which is basically captured by solar cells on the car roofs.

The release of Version 4.2a was an exciting event for us at COMSOL. I had the opportunity to see a preview of new products and the big one for me was the Particle Tracing Module. Many of our customers and colleagues in the simulation industry had been requesting this for quite some time. I must admit that I thought it was just because they wanted a different type of postprocessing feature; another way of looking at streamlines.

As most skilled COMSOL users, I am sure you know that you are not limited to just selecting what is in our drop-down lists. Say that you have invented your own measure of structural stress. You want it to be equal to the quadratic mean of the Tresca and von Mises stresses. Go to Plot Parameters to find out what these predefined stresses are called (tresca_smsld and mises_smsld if you are modeling in 3D with the Structural Mechanics Module). Now […]
