Prof Bert Blocken Kicks off CFD MOOC This Month

“Sports and Building Aerodynamics”, MOOC with Professor Bert Blocken

“Sports and Building Aerodynamics”, MOOC with Professor Bert Blocken

A fun and interesting online course to learn fluid mechanics and CFD as well as how they are applied to sports and environments around buildings is coming up soon. In his MOOC (Massively Open Online Course) entitled “Sports and Building Aerodynamics,” Professor Bert Blocken of Eindhoven  University of Technology (TU/e) plans to introduce wind tunnel testing and the use of ANSYS CFD. The course begins April 28, 2014.

You might have wondered about how aerodynamic shaping of cars, bikes, etc. affects the win/loss or margin of victory in a race. This course will give you insights about how the physics shapes these objects and influences performance. Continue reading

As We Say Goodbye to Sochi … Let’s Start Working on Pyeongchang!

Wow, the 2014 Olympic Winter Games in Sochi have been amazing and make me even more impatient to go to skiing in early April. I’ll especially remember three of the sporting events. First, Bart Swings from Belgium finished in fourth place in the 5,000-meter speed skating just behind a fully Dutch podium. Maybe aerodynamic simulation could have improved his performance and delivered him a place on the platform. There was also some great ski jumping where the skiers literally flew, and I found a flapping ski to perfectly illustrate fluid–structure interaction. I don’t know if this flapping is good or bad for performance. What do you think? Finally, I’ll remember the breathtaking downhill race. Continue reading

The World Cup is Already a Success for Brazil!

Tomorrow, December 6, is an important day for many because it’s the final draw that will deliver the verdict on the eight football (soccer) groups that will kick off the 2014 FIFA World Cup — one of the most popular sporting events in the world, surpassed only by the Olympic Games. The 2014 World Cup will take place in Brazil from June 12 to July 1. This year will be special for me because, for the first time since 2002, Belgium has qualified. The team from Belgium includes a large number of players from prestigious European championships, so we have a fair chance to go quite far in the competition.

Whether the Belgian team will be a tough competitor or an easy seed could influence the rest of the World Cup. Unfortunately, it is very unlikely I will be able to support our Belgian Red Devils in person in Brazil next summer. But I’ll feel a part of the event thanks to the remarkable work done under the auspices of NOVACAP, Maruska Holanda and Pedro Almeida performed by Prof. Paulo de Mattos Pimenta and ESSS, the ANSYS channel partner in South America.

The Stadium That Will Host the 2014 World Cup

Because a stadium is usually considered a prestigious landmark that is expected to last for decades, the quality of the design is crucial. The stadium must be able to withstand any situation it might experience during its lifetime such as heavy wind or cheering crowds. Continue reading

ANSYS Employees Take on Tour de France’s Toughest Slope

A year ago we were all amazed by the daring achievements of so many athletes during the Olympics. We discussed the impact of engineering simulation for these elites in a special edition of our ANSYS Advantage magazine. Personally, I look forward to each summer in July, when I watch with great admiration as cycling athletes embark on the route of the Tour de France. Once again, I’m very proud that ANSYS is somewhat part of the race through our clients.

Slide2Like most others, I’m impressed by the mountain ascents, watching the leaders who climb these slopes at an amazing speed. But I also respect those behind the leaders, who reach the summits with the thought of assisting their teammates the day after. Geographic names like Alpes D’Huez, Galibier, Col de la Madeleine and, of course, the beast Mont Ventoux, the giant of Provence, all sound like exceptional challenges reserved for an elite pack.

How Quickly Can I Ski Again, Doc?

image skiAs the ski season gets into full swing, friends who recently suffered a sprain or had a total hip arthroplasty (THA) (implanted hip prosthesis) are wondering whether they will be able to hit the slopes this year. Did you know that 400,000 American had a THA this past year? How long after a THA must they wait before skiing? And beyond that sport, before they are jogging or biking again? Most doctors offer a conservative approach, allowing for full recovery before pursuing such rigorous sports. Their judgments are based on the average recovery of a large group of patients, throwing in a reasonable safety margin to try to avoid joint deterioration.

If you’ve had to endure the seemingly never-ending recovery period of THA, you’ve no doubt felt the frustration of feeling perfectly fit to go skiing, probably just before the season ended. Too soon, according to doctors’ recommendations. But let’s imagine imagine a more hopeful scenario: that your doctor could evaluate (for you as an individual patient, not an average) whether the risk of injury practicing your favorite sport is indeed real. Will the exercise induce too large a movement between bones and implant, thus preventing proper healing? Would the stress in your weakened ankle be too great, leading to a new injury? Could you at least start some light training again? If only we could estimate the exact stress induced by various movements in the different parts of the body, we would know for sure if we can get back in the game or need to rest further.
