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.

Learning how to use computational tools requires training. This is why a large group of stakeholders — one that continues to grow — relies on a small pool of experts to perform simulation analyses. The Application Builder, part of the COMSOL Multiphysics® software, is helping to bridge this gap. Simulation experts can now wrap models in an easy-to-use interface, making multiphysics simulation more accessible to a wider audience. See what our customers have to say about the Application Builder.

Today, we invite guest blogger Rune Thygesen of Reelight to discuss designing a power generation source for bicycle safety lights using simulation. At Reelight, we are developing an affordable bicycle safety light that is extremely easy for the end user to install. Along with a stronger and more flexible mounting system, we needed to develop a new power generation platform. Using simulation-based design, we created a power platform that is easy to use and quick to install.

Today, we invite guest blogger Bauke Kooger of Delft University of Technology to discuss modeling a magnetic suspension system for the Hyperloop. The Hyperloop is a proposed mode of transportation in which a vehicle, or pod, travels at the speed of sound through a low-pressure tube. At this speed, a magnetic suspension offers several advantages over systems such as air bearings or wheels. To test this, Delft’s Hyperloop team modeled their pod’s magnetic suspension in the COMSOL Multiphysics® software.

Today, guest blogger René Christensen of GN ReSound discusses the importance of acoustic topology optimization and how to apply it in COMSOL Multiphysics. Topology optimization is a powerful tool that enables engineers to find optimal solutions to problems related to their applications. Here, we’ll take a closer look at topology optimization as it relates to acoustics and how we optimally distribute acoustic media to obtain a desired response. Several examples will further illustrate the potential of this optimization technique.

Developing a device that generates nuclear fusion would provide a nearly limitless amount of clean energy on Earth. But while work on thermonuclear fusion began in the 1950s, engineers are still trying to make this goal a reality. One approach has been to use magnetic confinement devices known as tokamaks. See why a group of engineers at MIT’s Plasma Science Fusion Center (PSFC) turned to simulation to address a key challenge in tokamak design: instability due to plasma disruptions.

We rely on power transformers for everyday tasks, but these devices also create a loud buzzing or humming noise. This sound comes from vibrations in different parts of the transformer and is impossible to eliminate completely. To reduce the noise, a team of engineers at ABB Corporate Research Center simulated the acoustic, electromagnetic, and mechanical behavior in their transformer systems with the COMSOL Multiphysics® software.

Acoustic measurements aren’t always accurate due to imperfections in the measurement tools. To limit incorrect results, devices, such as microphones and vibration transducers, have standards that define their allowable margin of error. Meeting these standards is required, but good measurement tools go a step further and keep their error range consistent over time. To create quality devices, research teams at Brüel & Kjær use multiphysics simulation to model their microphone and transducer designs.

As technology evolves, the demand for devices with greater features and functionality emerges. Of course, this means that the designs themselves become more intricate and complex. Simulation offers an efficient route to analyzing and optimizing such devices, prompting further industrial innovation along the way. Today, we’ll take a look at how a team from University of Buffalo designed multiphysics models and simulation apps to spread modeling expertise to a broader range of industries.

For gas pipeline maintenance standards, the adage “rules are meant to be broken” may not apply, but “rules are meant to be updated” certainly does. Specifically, the generous distance requirements between pipeline squeeze-off locations and pipe fittings cause potentially unnecessary digging. This prompted Operations Technology Development (OTD), a partnership of natural gas distribution companies, to initiate a project with Gas Technology Institute (GTI), where researchers used simulation to investigate the standard distance requirements for streamlined and safe pipeline maintenance.

The magnetostrictive effect causes magnetic materials to change their shape when a magnetic field is applied. Materials that exhibit such behavior are used in a range of devices, from loudspeakers to actuators. In order to analyze one type of device, a magnetostrictive transducer, researchers from ETREMA Products, Inc. performed single-physics and multiphysics simulation studies in COMSOL Multiphysics. See how the flexible nature of the software enabled the team to study various aspects of the device and optimize its overall design.
