Investigating the Fundamentals of an “Old” Technology
Transformers were first commercially used in the late 1800’s, but they are still being investigated at their fundamental levels. One of the stories from our latest COMSOL News concerns ABB (who themselves have been around since the late 1800’s) and their research into these apparatuses.
Another Danger with Corrosion
One dangerous aspect of corrosion is that it can compromise the stability of structures, which is particularly relevant in the naval industry, where material failure leads to leaks. However, another danger of corrosion has recently become apparent.
News in Particle Tracing for 4.3
There are many exciting new features in the Particle Tracing Module for COMSOL Multiphysics version 4.3. The secondary particle emission feature is particularly fascinating. “This new option for the Wall Condition allows you to model filter multipliers and multipactors, which were previously very difficult to model”, says Dan Smith, Development Team Leader at COMSOL. A mathematical expression, like a logical expression containing the particle energy for instance, can be used to determine the number of secondary particles to be released. […]
Report from Well Logging Workshop in Houston
On the 17th of May, 27 engineers and scientists related to the oil and gas industry gathered in Northwest Houston to learn more about COMSOL Multiphysics applications for well logging. This area of research and development is of particular interest to the oil services companies, who make tools that help maximize the output from wells. These tools are highly advanced technological devices. They work by being inserted into a wellbore and detecting how much hydrocarbon (e.g., oil) is in the […]
AltaSim Takes on Surface Plasmon Resonance Modeling
We’ve just got another finished article and layout back for COMSOL News and it looks as great as the others, but for different reasons. We usually ask a couple of our partners to write an article for COMSOL News to provide users with some more technical background to modeling. AltaSim Technologies, who are certified consultants and even run courses in COMSOL, have written an article about surface plasmon resonance.
Design Materials to Exhibit Wanted Properties
I’ve just been reading my favorite news service, www.physorg.com, and noticed that cloaking is once again the topic of the day. While we have previously reported on a group out of Duke University, this article mentions a group from Ames Laboratory in Iowa. Similar to the Duke Group, Costas Soukoulis from Ames Laboratory also seems to have been at the forefront of this research.
Now There’s Thermal Cloaking
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.
What Is the Nature of Pain?
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.
