Keynote Video: Modeling the Multiphysics Behavior of Nuclear Fuel

Bridget Paulus November 6, 2017

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.

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.

Have you ever tried to plot multiple quantities on one graph, only to realize that the scales don’t match up? You can solve this problem by adding a second y-axis to your 1D plot to include two scales of values. In the video below, we introduce a case where you would want two y-axes. We then show you how to add a second y-axis to your graph and create helpful annotations in the COMSOL Multiphysics® software.

When making improvements to a model in the COMSOL Multiphysics® software, you are likely to add more parameters and variables. As the complexity of your model grows, it can become difficult to keep track of where these parameters are being used and defined, as well as to recall them for use in the settings of other nodes. In this blog post, we show you how to use the Auto Completion and Find tools for efficient model setup.

The Open Recovery File feature is a somewhat unknown feature in the COMSOL Multiphysics® software, but it’s useful for anyone running simulations that give multiple solutions. If, for any reason, the software shuts down before the simulation finishes, you can open a recovery file so that you don’t lose your work. Here, we highlight a tutorial video on how to open these files to recover “lost” work as well as go over the strengths and limitations of this feature.

For those looking to solve complex transport process problems involving photonics and microfluidics, it can be challenging to account for all of the elements involved, including multiple physics phenomena. However, this is necessary for accurate results. By using multiphysics simulation, Carl Meinhart from the University of California, Santa Barbara and Numerical Design, Inc. accurately modeled transport processes in two application areas: high-frequency acoustics and microfluidic valves. Watch his keynote talk from the COMSOL Conference 2016 Boston to get the details.

When a pipe springs a leak, it’s important to find its location with a quick and accurate method. Engineers at Echologics — a Mueller Technologies Company — use a combination of acoustic sensors and simulation applications to pinpoint such leaks. Sebastien Perrier of Echologics discussed the benefits of this approach and gave a live demonstration of an acoustics modeling app during his keynote talk at the COMSOL Conference 2016 Boston. If you missed Sebastien’s presentation, you can watch it below.

When designing needles for drug delivery, one major challenge is balancing the comfort of the patient with the effectiveness of the injection. By applying an approach that combines “first principles” thinking and modeling, Eli Lilly and Company optimized the design of a needle for an insulin injection pen, while keeping patient experience in mind. In a keynote talk from the COMSOL Conference 2016 Boston, Bernard McGarvey of Eli Lilly discusses this process.

To optimize your modeling processes, there are a number of built-in materials available for you to use in the COMSOL Multiphysics® software. Along with these materials are features and functionality that allow you to efficiently assign materials to geometric entities in your model. These tools help expedite the process of assigning materials, specifying material properties, and even comparing the impact of different materials on your simulation results. Here, we’ll highlight three tutorial videos that showcase how to use such tools.

When you are creating a model, it can sometimes be difficult to keep track of all the parts in the geometry, including the conditions or constraints that apply to each section. This is especially true when dealing with large, complex geometries and multiple physics interfaces. In COMSOL Multiphysics, tools like named selections help maintain your model setup and streamline your workflow. Here’s a look at three tutorial videos demonstrating how to create and utilize Explicit, coordinate-based, Boolean, and adjacent selections.
