As an academic organization within the University of Palermo (Italy), our Zyz Sailing Team brings together students and professors with a shared passion for the design and manufacture of a racing sailboat. Our members have particular skill sets. Some are experienced with engineering design elements, such as CAD, the finite element method (FEM) and computational fluid dynamics (CFD), while others are expert craftsmen.
We began designing and building small sailing boats in 2008. Our latest challenge was the creation of Ercte, a 16-foot foiling catamaran constructed of marine plywood and carbon fiber reinforced plastic.

My house has a 30 Mb/s internet connection that I use to stream entire movies. I talk to people on the other side of the world and participate in virtual meetings on my mobile phone, which fits in my pocket and works everywhere. I also use my mobile to drive through cities I’ve never seen before, following the best route as determined from satellites in space that track the location of my phone using GPS coordinates. You are probably thinking “so what?” because you, like billions of other people, have the same kind of connectivity. This is what should impress you most: We are so used to this easy connectivity that we have forgotten how incredible this technology is compared to what we had 20 years ago. Engineering simulation played a big role in getting us to this point, and it will play and even bigger role in the future. Continue reading
I think I figured it out. The Patriots might be using real-time CFD simulation to raise their field goal percentages.
As anyone who watches the NFL knows, the Patriots are perennial winners. With their third Super Bowl appearance in the last four years, it seems they have an automatic ticket to the big game. However, all six of their appearances in the last 14 years have been close, coming down to 4 or fewer points. A single missed field goal could have sent the Lombardi trophy to a different team.
Fortunately for the Patriots, their kicking game is top notch. New England has finished in the top 5 in made field goal percentage in 4 of the last 5 years, with a league best 94.6% made field goals in 2014. Is this because they only attempt conservative kicks, or play in a closed stadium? In fact, it is quite the opposite. Continue reading
Triton UAS (unmanned aerial systems) is a project team from the sunny campus of the University of California, San Diego. We are a student-run team that uses ANSYS CFD solutions to help in designing, building, testing and flying our UAV to compete each year in the Student UAS Competition hosted by the AUVSI Seafarer Chapter against teams from around the world. The goal of the competition is to promote autonomous flight. Despite the fact that the 2017 competition coincided with finals week, our team placed ninth overall out of 42 teams.

Sales of electric vehicles (EVs) are skyrocketing. Driven by technological improvements in powertrains and batteries, environmental regulation, and shifting consumer demand for greener vehicles, global sales of EVs rose by 40 percent last year. And the electrification revolution is only getting started. This growth trend will continue as the cost of owning electric vehicles declines and approaches the cost of internal combustion engine (ICE) vehicles sometime within the next decade.
In a previous blog, I noted that born in the cloud companies can be a boon to tech startups looking to optimize precious resources. In this post, I offer a spectacular case in point.
Optisys had big goals and big compute needs. Designing its next-gen antenna, the Utah-based startup sought order-of-magnitude reductions in size, weight and lead time, and a cost-effective solution for running large, concurrent RF electronics simulations. Establishing an in-house IT function wasn’t an option: Optisys (like many startups) had little appetite or budget for investing outside its core business. Instead, it adopted Rescale’s cloud-based platform to satisfy its simulation needs. Continue reading
Safety first — especially when it comes to engineering control systems for autonomous vehicles. These systems must meet the same high-level safety standards long-mandated for aerospace and defense technologies. In addition, the operating systems that run the certified programs must also be safe — from hackers.
Together, ANSYS and Green Hills Software have developed a comprehensive solution for driverless cars that rises to the level of ISO 26262 (ASIL D) certification and is invulnerable to hacker attacks. Continue reading
In a few days, I’ll be in Florida at the AIAA SciTech Forum, along with some of our technology experts. This is the place where you can get an inside look at how much innovation is going on in the aerospace industry today. At ANSYS, we are constantly expanding our simulation platform capabilities through internal development and integration, acquisitions and partnership. Let me highlight just a tiny part of what happened in 2017 and what you can “touch” at our booth at SciTech.
You may be surprised to learn that a standard passenger jet can have 30 to 50 antennas protruding from the aircraft’s external surface, producing drag forces that can drastically reduce fuel efficiency at a time when airlines are trying to reduce energy consumption. Most antenna designs are engineered for safety purposes, such as air traffic control, traffic collision avoidance, instrument landing systems and distance measuring equipment. Increasingly, antennas are being added to meet passenger demand for more and faster Wi-Fi access, in-flight TV and cellphone applications.
Antennas are mounted on the exterior of today’s airliners
As students at the University of Florence, we aren’t just racing to class, we’re racing around Europe. Last season was particularly exciting for our 35-member Firenze Race Team (FRT). We designed two new single-seater cars — the FR-17T and FR-17DT — and introduced them at Formula Student competitions in Italy and Germany.
