What’s in a Name?

Phil Kinnane March 8, 2012

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.

Someone who saw my RFID model blog post from a few days back pointed me towards a site that talks just about RFIDs. On it, I discovered a lot of articles about using RFID in the biomedical industry. This was an application that I had never thought of before. I’d always associated RFIDs with security, tracking packages and the like.

While thinking about the blog post I published previously, about the hemisphere spiral antenna, I came across this article about RFIDs. Radio Frequency Identifications are small, inexpensive chips, which use RF to send stored information while being fixed to almost any gadget or personal effect.

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.

The blog post I wrote about Intel’s Concurrency Test produced some traffic, so I thought I would follow it up with some resources we have to support our users interested in modeling with clusters. First, I noticed a hugely popular thread in our Discussion Forum, with almost 11,000 views on the subject.

One of the things I do at COMSOL is to make some of the images we use in our marketing material. I was working on a picture of a piezoelectric microtweezer for an ad that would be used for our MEMS Module, as the one you can see below. That’s when I started wondering what these microtweezers actually do.

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 noticed a lot of activity when I posted the question concerning “FEM vs FVM” in a previous blog post, so I started looking into it a bit. A lot of people went to the COMSOL Discussion Forum thread on the matter, from the blog, which got me thinking that this must be a hot topic out there. Not Much Debate How disappointed I was when I typed ‘FEM vs FVM’ into Google and saw that there wasn’t much to […]

I’ve just been working with Roger Pryor, as he gathers material for his new book. Roger wrote a book called “Multiphysics Modeling using COMSOL” a couple of years ago that turned into a good seller. Now he has released “Multiphysics Modeling using COMSOL Multiphysics v.4”. This is the first book I am aware of that showcases Version 4.

An interesting discussion has been going on in the COMSOL Discussion Forum. What is the difference between the Finite Element Method (FEM) and the Finite Volume Method (FVM)?
