At the COMSOL Conference 2017 Rotterdam, simulation specialists from across Europe (and some from as far away as Chile and South Korea) showcased their innovative research and modeling work. Among the many excellent user presentations, several made a special impression and were recognized with awards. Read on to learn about the top papers and posters from the COMSOL Conference 2017 Rotterdam.

Einzel lenses are used to focus charged particle beams in cathode ray tubes (CRTs). To properly analyze an einzel lens, we need to study the charged particles in the lens subject to appropriate electrical excitation. Here, we discuss one such example that uses the Particle Tracing Module, an add-on product to the COMSOL Multiphysics® software.

Skyscrapers, highway bridges, and other heavy manmade structures often use drilled shafts. Despite their widespread application, these shafts suffer from anomalies due to suboptimal designs and issues with the flow of concrete. To better understand such problems and improve the concreting process for drilled shafts, researchers used the COMSOL Multiphysics® software. Here, we take a peek at their preliminary research and findings.

Suppose you have a very long system with a constant cross section: a fluid-filled pipe. Modeling this system is computationally expensive and time consuming. Using a guided wave propagation approach, you can model a cross section of the system and compute the guided waves along it. You can represent such waves by means of dispersion curves. Here, we discuss a coupled analysis considering air and water as the internal fluids. We also analyze the system dynamics using dispersion curves.

From cocktail parties to public transit, there are competing sound sources in many everyday environments. If you want to listen to one specific sound, say a friend’s question, in a complex auditory setting, you have to distinguish between the sounds around you and focus on the one of interest. This situation is known as “the cocktail party problem”. Understanding how humans solve this problem can lead to advancements in hearing aid designs.

Optimizing fuel for nuclear reactors can increase the amount of power they generate, improve their safety, and lower greenhouse gas emissions. However, studying nuclear fuel can be complex, as it involves interactions between multiple physical phenomena. In his keynote talk from the COMSOL Conference 2017 Boston, Andrew Prudil of Canadian Nuclear Laboratories (CNL) discussed using multiphysics models to gain insight into nuclear fuel. If you missed his presentation, find a video recording and summary below.

In structural mechanics, there may be situations when you want to implement your own material model. The COMSOL Multiphysics® software gives you the option to program your own material model in C code. The compiled code can then be called from the program using the External Material feature. Here, we demonstrate how to implement an external material model and then use it in an example analysis.

You’re listening to music when you bump into your loudspeaker, knocking it off the table. Fortunately, it still works! In his keynote presentation at the COMSOL Conference 2017 Boston, Richard Little discussed how Sonos, Inc. ensures that loudspeakers are durable enough to withstand certain stresses and how they use simulation to improve the robustness of the transducer component. If you missed his talk, you can watch the video recording below, followed by a quick summary of his presentation.

My favorite novel to read around the Halloween season is Stephen King’s It. A common misconception about the book is that “It” is just a scary clown — It is actually the embodiment of whatever you fear most. If what scares you the most is the possibility of ghosts, don’t worry: a researcher used acoustics analysis to explain that whatever scares you this Halloween, like It, is just a trick of the mind (and vibroacoustic effects…)

Earlier this month, simulation engineers and researchers presented their posters and papers at the COMSOL Conference 2017 Boston. Six papers and posters were selected to win awards, and conference attendees also voted for their favorite poster presentation. Interested in learning which papers and posters among the many great contributions were named award winners? Read on.
