Keynote Video: Using COMSOL Server™ for Product Development

Fanny Littmarck December 18, 2017

In a lineup of online shopping results, jackets labeled as being made with GORE-TEX® product technology signal “high quality” to the consumer. The company behind this technology, W. L. Gore & Associates, Inc., specializes in materials science for fabrics, medical products, and performance solutions. The companies that produce the end products rely on material that performs as expected. To accelerate their product development efforts, W. L. Gore & Associates, Inc. uses simulation, apps, and the COMSOL Server™ product.

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.

Keynote Video: Using Simulation to Develop Reliable Audio Transducers

Caty Fairclough November 1, 2017

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.

How to Create Graphs with Two Y-Axes in COMSOL Multiphysics®

Andrew Griesmer July 27, 2017

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.

How to Use the Find and Auto Completion Tools for Faster Model Setup

Amelia Halliday May 8, 2017

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.

How and When to Open Recovery Files in COMSOL Multiphysics®

Andrew Griesmer February 7, 2017

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.

Keynote Video: Solving 2 Transport Process Problems with Simulation

Caty Fairclough January 19, 2017

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.

Keynote Video: Locating Leaks in Pipe Networks with a Simulation App

Bridget Paulus January 16, 2017

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.

Keynote Video: Combining First Principles Thinking and Modeling

Brianne Costa January 3, 2017

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.

Efficiently Assign Materials in Your COMSOL Multiphysics® Model

Amelia Halliday September 20, 2016

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.
