Lightning-Proof Wind Turbines
Here’s a story we’ve all heard before: due to the inefficient nature and inevitable decline of fossil fuels, alternative energy resources are becoming increasingly popular. Wind energy is a popular source of alternative energy, with wind farms sprouting up all over the world. Here’s something you may not have thought about: lightning strikes are a major problem for these wind turbines. Intuitively, places with high wind speeds also have stormy weather, and a 150 meter tall metal pole makes an […]
Keynote Video: Multiphysics Simulation for Patient Safety
The second video in our COMSOL Conference Boston 2012 keynote series features Dr. Alan Leewood’s presentation on the use of multiphysics simulation for medical safety applications. The focus of this presentation is on the safety of passive conductive implants during MRI screenings.
Simulation-Based Design of New Implantable Hearing Aids
Growing older is an inevitable part of life, and with it, our body slowly begins to show that. I recently started wearing eye glasses because my eyesight is weakening. It’s a little unnerving, but I am comforted by the ever-improving technology being produced. My hearing is still fully intact, but the same cannot be said for 17% (36 million) of American adults who report some degree of hearing loss. In most cases, regular hearing aids are sufficient in treating hearing […]
First Keynote Video Takes Us to Babel
One of the differences between this year’s COMSOL Conference, and previous years’, is that this year we filmed a lot of it. During the next few weeks we will be publishing some of these videos for those that were there, to enjoy it once again, and for those that weren’t to get a taste of what went on. To kick these all off, I’m proud to present the first keynote video, which takes us to Babel.
Proprietary Code or Off-the-Shelf?
Many engineers and scientists have worked in their chosen application areas for many years. It is not unusual that their first models consisted of a few lines of code that they wrote themselves. Or, the application was so specific that the engineer was forced to write code, as none of the commercial simulation packages available could handle their unique application. Then there’s the COMSOL Multiphysics® software, which enables you to enter your own equations. What’s the best option?
Coal: The Energy of Right Now
While alternative energy is the energy of the future, fossil fuels are the energy of right now. Coal, especially, is still heavily relied on for energy production and is a primary source of electricity generation in many countries including the US and China. In fact, world coal consumption is actually increasing year-to-year. Scientists need to be concentrating on how to make alternative energies more widespread, but they also need to make coal a better, more efficient fuel source. Designing systems […]
New Product Video Tutorial: LiveLink™ for Solid Edge®
With the latest COMSOL release, Version 4.3a, comes new CAD interoperability. We are delighted to introduce LiveLink™ for Solid Edge® seamless associativity between Siemens’ CAD experience and COMSOL’s multiphysics simulation software. A LiveLink™ for Solid Edge® video tutorial demonstrates this integration, and gives you a leg up in your design modeling. In this video, the three main features to help you design, optimize, and troubleshoot your geometries are demonstrated.
Modeling Scar Effects on Electrical Spinal Cord Stimulation
Spinal cord stimulation (SCS) is a treatment for chronic back pain that has been around for over 40 years. It involves implanting electrodes that apply electric potentials directly to the spine, interfering with the human pain signaling circuitry. The body attempts to send pain signals to the brain, but the electrodes act as a barrier preventing the signals from reaching the brain. Although an overall successful method for treating back pain, researchers have been improving on the design since the […]
