Tomorrow, December 18th, we are holding an online tutorial on piezoacoustic optimization. The tutorial will run for about half an hour starting at 12:30pm Pacific Standard Time (PST). If you are already familiar with the piezoacoustic transducer model in the model library, you should tune in for this further-developed version of the model.

A while back, I wrote about permanent magnet generators and how they generate electricity upon being set in motion. When browsing the papers from our conference in Bangalore, one on the topic of ultrasonic micro motors caught my eye. These motors are electromechanical in nature and instead initiate motion with the application of an electric voltage. Furthermore, these motors are miniaturized to fit a micro-scale environment.

The latest version of COMSOL Multiphysics features a brand new way to use COMSOL. With LiveLink™ for Excel® you can modify and run COMSOL models in Microsoft Excel® 2007 or 2010. This combines the familiarity of Excel® with the physics simulation capabilities of COMSOL. Thus, making it easy for users of Excel to run multiphysics simulation without operating COMSOL themselves. A new LiveLink™ for Excel® video tutorial demonstrates the powerful combination. In the video, the main features to help you model and present in Excel® are demonstrated.

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 attractive target for lightning strikes. In fact, some extreme wind turbine sites experience 10 lightning strikes a day!

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 loss, but beyond a certain level, a bone conduction implant or a cochlear implant must be installed.

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.

Many of the engineers and scientists that we collaborate with have been in the game for years. All of them are great experts in the applications that they want to model, and many of them are also proficient at computer science — it was not unusual that the first model or simulation of their application was a few lines of code they wrote themselves. Moreover, in a number of situations I’ve come across their application has been so specific that they’ve been forced to write code, as none of the commercial simulation packages available at the time have been able to handle the uniqueness of their application. But as commercial software has become more sophisticated and flexible, such as COMSOL Multiphysics’ ability for you to enter your own equations, this need is diminishing. So which is better? Proprietary code or off-the-shelf? And should you migrate your old proprietary code to a commercial package?
