News in Particle Tracing for 4.3

Fanny Griesmer June 1, 2012

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. […]

COMSOL News is now available in print and electronically, and you can request your copy of the multiphysics simulation magazine here. One of the great stories concerns a process engineer at Ruukki Metals in Finland, Mika Judin, who not only uses COMSOL to model and optimize his process, but lets the operators use the simulation too.

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 […]

Knowing the sun’s radiation and thermal effects is very important to designers within the building industry, especially in designing “green” buildings. Heat transfer also plays a vital role in designing outdoor devices in terms of maintaining temperatures in extreme hot or cold environments. To use the words of Nicolas Huc, project leader for the Heat Transfer Module development at COMSOL in France: “it makes a huge difference if you forget to take the sun’s radiation into account.”

When it comes to the design of batteries, we want to maximize charge while minimizing volume and weight. The use of nanoparticles can help achieve these goals. However, as I was just reading in one of my favorite websites, Phys.org, it is very difficult to control the material properties when working with nanostructures.

“At 5:00 central time, June 5th 2012, Venus will transit the sun. It will not do so again until December 2117. The task at hand is to provide a live webcast of the transit as seen from Tulsa, OK.”

It’s an exciting time here as we’re starting to release a series of resources for COMSOL users and people interested in modeling and optimizing multiphysics and other engineering applications. This will be done as a set of CDs that will contain animated videos summarizing the features in COMSOL’s suite of products, and videos showing model examples being built. Also included on this CD will be white papers, conference articles, and reports of real-life situations where modeling has been applied.

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.

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.

It’s been fun working with the next release. One of the great new features will be in the Particle Tracing Module and will allow particles to interact with each other, and not only with the macroscopic field they find themselves in. It also produces some pretty cool vids.
