Feather or Synthetic Shuttlecock Design to Win the Game?

Every Friday night, I’m playing badminton with a few friends in my village of Perwez in Belgium. Beyond the motivation of staying fit and healthy while having good time, I’m also pushed by the strong desire to defeat my friend and colleague Michel Rochette from our Lyon office. Occasionally, we are organizing international games to challenge each other and so far, the results are very tight. But I now have a winning strategy!  Continue reading

Witnessing Engineering Simulation in Action

During the last few weeks, I had the opportunity of a lifetime to witness two competitive sport clients race with machines that were developed using ANSYS fluid dynamics engineering simulation tools. I can guarantee you that I was like a kid in candy store!

Emirates Team New Zealand - America's Cup

In September, I was on vacation in San Francisco to see the America’s Cup and had the chance to see Emirates Team New Zealand race. As you might recall, they won the Louis Vuitton Cup — but unfortunately not the America’s Cup. Even so, seeing those monsters race on the SF Bay was phenomenal. What a spectacle! Amazing sailing, impressive engineering.

Emirates Team New Zealand - San Francisco Bay

These are just a couple of the photos I took at the event. One shows the boat after the race. I thought it was a cool picture because it showed how massive it is. The other shows the actual wing.

If you want to know more about the America’s Cup and fluid dynamics simulation, please listen to the designer team of Emirates Team New Zealand talk about it here. Continue reading

Winning the America’s Cup with CFD and Optimization

Image of Camper ETNZ1Last year, I blogged about the Red Bull racing team and how they continue to win – thanks, in part, to CFD. Today, I ran across an interesting blog from a CFD engineer at Emirates Team New Zealand (challenger for the next America’s Cup).

Keep in mind that CFD for competitive racing is nothing new. But, thanks to the article, I learned about an innovative use of CFD to develop winning boats. In the case of Emirates Team New Zealand, the computational fluid dynamics data was actually fed to a performance simulator. This sounds straightforward … or so I thought. This performance simulator requires a large amount of data, and the team had to test hundreds of designs and trims each week! The thing that amazed me is that they didn’t need to test some of them — and not just a dozen of designs per week, but hundreds of designs every week. Such a high level of CFD usage to determine the optimal boat performance is amazing. Continue reading
