This week’s Top 5 engineering technology articles include some of my favorite topics, space, Tesla, but also some news in the cycling world and a video that’s out of this world (almost).
Our story began in the afternoon of Monday, June 15, 2015. It was just like any other day until an email with SpaceX’s announcement of a Hyperloop competition was received. We got to thinking and within a week, BadgerLoop was created purely by word of mouth. 15 students worked from around the world, while on summer internships, to solidify the core of BadgerLoop.

If you’ve heard anything about ANSYS 17.0, it’s that it is faster than ever. Faster solvers, faster processing, greater core counts — it all sounds great, doesn’t it? Everyone wants to get their work done faster, and faster is better than slower, isn’t it? But what exactly does “faster” mean to engineers performing structural analysis simulations today? Continue reading
In the five short years that I have been in the RF and Microwave design industry, I have seen the demand (and need) for quick and accurate electronic design simulations escalate rapidly. I have also had the opportunity to interact with many design engineers during this time who have come to the same conclusion – they need more accuracy. Whereas ideal component simulation models or s-parameter files were once acceptable, this is much less often the case now. Parasitics have a considerable effect on component response, and even more so as design frequency increases. Labor and material costs multiply with each design iteration, so it is very important to limit these cycles and achieve a successful design early on. Continue reading
Delivering a truly innovative product for the mobile revolution requires optimization at every level of design for power, performance, thermal and structural integrity. The success of today’s electronic products are tied to the success of their entire system, including all components from antenna to board, and from chip to chassis. Designing a smart watch, for example, requires multiple iterations of chip, package, board, antenna, and cooling strategy to arrive at a final optimized product. Continue reading

Hello all! My top engineering technology picks of the week include one company creating hybrid planes, new technology for your car that lets you control your phone from the steering wheel and a new exoskeleton that is helping the paralyzed walk. Have a great weekend!
Turbomachinery designers are under pressure to improve all aspects of turbomachinery performance. That applies not only to aircraft engine developers, who sometimes seem to garner the most attention in the news, but to designers of most other machine types as well. While fuel burn and efficiency targets are most often discussed, these targets must be balanced with a number of other competing and often opposing considerations, such as operating range, reliability, cost, time to market, etc.
Engineering simulation now plays a key role in turbomachinery development. This has come about because of significant improvements in engineering software and computing speed. Many turbomachinery companies were early adopters of simulation; they played a significant role in shaping software development to their needs and validating it for their applications. Experiment and testing still play an important role, but often only when a design is sufficiently evolved, or in situations where fundamental information is missing. So simulation and testing complement one another. Continue reading
Fidelity and accuracy is critical in CFD simulation. After all, physical prototyping and testing can only be reduced and even replaced by CFD if one can expect accurate results. Up to now, high fidelity, high accuracy results came with a price. Complex geometries — the realistic, no holds barred type — required hours of manual effort to clean up the model and then prepare the mesh. Users were tempted to cut corners and take short cuts that sped up prep but took a toll on accuracy and fidelity. Unfortunately, there is no way of knowing just how those inaccuracies skewed the results, putting any recommendations in doubt. For example, if you don’t resolve a boundary layer correctly then any aerodynamic drag figures could be highly inaccurate. Continue reading
Every day between now and February 7th will turn up the excitement about the biggest day of American football, the SUPER BOWL. It will take place right here in the San Francisco Bay Area. Promoters are calling Super Bowl 50 the biggest Super Bowl ever.” Starting with the Run the Road to the Super Bowl 10K, 5K Run on January 10, to the Metallica and Cage The Elephant concert the night before the big day, events will be hosted to entertain all. This makes me think of football and football concussion.
