The 10th Annual COMSOL Conference Takes Place in 2014

Kristen O'Connor | January 22, 2014

We’re kicking off the new year right with the announcement of our COMSOL Conference 2014 tour dates and locations. This year marks the 10th annual COMSOL Conference and we have a lot of exciting things planned for you. Not only are we enhancing our program, but we have also added locations to the conference tour. Here’s a look at what to expect and in what locations.

We would like to welcome you to visit our brand new MEMS and Piezoelectric Device Showcase — a free, one-stop digital resource geared to inform you on the physics, applications, and industries as they pertain to modeling MEMS and piezoelectric devices. In the showcase, you will learn about a host of applications that can benefit from utilizing COMSOL simulation software. Rich content including videos, case studies, presentations, and example models are provided to help paint a clearer picture of everything […]

We often want to model an electromagnetic wave (light, microwaves) incident upon periodic structures, such as diffraction gratings, metamaterials, or frequency selective surfaces. This can be done using the RF or Wave Optics modules from the COMSOL product suite. Both modules provide Floquet periodic boundary conditions and periodic ports and compute the reflected and transmitted diffraction orders as a function of incident angles and wavelength. This blog post introduces the concepts behind this type of analysis and walks through the […]

With shrinking electronic devices and ever-increasing power densities, efficient thermal management is at the heart of many R&D activities for electronics engineers. When developing complete systems containing multiple components, designs can become rather complex. An example of such a design would be a computer power supply unit (PSU), which can include not only electronics, but also multiple heat sinks, cooling fans, perforated grilles, and other large components — all within a small enclosure. In this blog post, we will explore […]

It’s easy to navigate from place to place thanks to GPS, but what about once you actually get there — what about navigating indoors? From venues of leisure to buildings in flames, there are many situations where indoor location tracking is useful. GPS technology does not work inside buildings, but there are now other methods under development that will make indoor navigation possible as well.

Spectroscopic imaging has been used for decades to map the chemical composition of material surfaces with atomic-scale resolution. In order to achieve adequate chemical specificity and spatial resolution during imaging, both the material sample and the imaging system are placed under high or ultra-high vacuum (UHV). In practice, materials are often used outside of vacuum environments and therefore it is also necessary to evaluate their surface properties at higher or ambient pressure. Differential pumping is the key to designing vacuum […]


Jeff Crompton | January 20, 2014

Today we have the pleasure of introducing Jeff Crompton, a guest author from AltaSim Technologies, who will discuss ceramic matrix composites and how to accurately analyze the production of such an advanced material. Ceramic matrix composites (CMCs) are fast becoming popular in many industries due to their ability to withstand high temperatures, corrosion, and wear better than metal components. They are being used in space applications, burners and combustion chambers, gas turbines, brake discs, and slide bearings. The manufacture of […]

Whether you are interested in an introduction to COMSOL Multiphysics or want to delve deeper into application-specific courses, you will want to check out the newly released 2014 Training Course series. This is your opportunity to advance your simulation skills and maybe show off to your colleagues how quickly you can set up and solve a complex model. At a COMSOL training course, you can learn tips and tricks from skilled application experts as well as the modeling of applications […]

Many of our users are well aware of the fact that COMSOL Multiphysics can be used to solve partial differential equations (PDEs) as well as ordinary differential equations (ODEs) and initial value problems. It may be less obvious that you can also solve algebraic and even transcendental equations, or in other words, find roots of nonlinear equations in one or more variables with no derivatives in them. Are there real applications for this? Absolutely!

Charged particles (such as ions and electrons) are susceptible to electromagnetic fields that exist in the space they occupy. Macroscopic and microscopic particles (dust, pollutants, etc.) are primarily susceptible to forces due to the background fluid (liquid or gas) in which they reside. Particles may also interact amongst each other, or influence the surrounding fields. For systems such as particle accelerators, aerosol distributors, and filtration devices, it can be helpful to calculate particle trajectories or know where the collisions and […]

When you are working with foreign CAD data, such as files in STEP or IGES file formats, you may think that you need to re-import a new CAD file and start your modeling over from scratch if you want to study a change in size or shape. But, in fact, you can modify the geometry that you’ve imported with some clever usage of the Deformed Geometry interface in COMSOL Multiphysics. Here, we will look at how this can be done.
