If you are a regular reader of this blog, you may remember the post I wrote about witnessing simulation in action at the endurance race in Austin, TX. Since that great experience, I have been following the 2013 FIA World Endurance Championship in general, and the AF Corse team in particular (the AF Corse team races with Ferrari F458 cars). There is only one race left — the 6 Hours Endurance of Bahrain (Kingdom of Bahrain).
AF Corse won the 2012 FIA World Endurance Championship and is currently second in the 2013 season, just 8.5 points behind the leader. I will be following the next race on November 30th and be cheering for the team!
You may wonder, why? Am I an automotive sports enthusiast? Not really. Do I love the Ferrari F458 because I own one? Definitely not (not even on lease!). I am following the races and the Ferrari team because I am amazed at how they used CFD simulation to design the Ferrari F458. Now, we all know about using CFD for aerodynamic, engine cooling, etc. But something that amazed me is how they used CFD simulation to design the side rear view mirror. You may be thinking, of all the components, this one does not look very important for the aerodynamic of the car, so what is cool about that? Here is the story. Continue reading
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!
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.
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

ANSYS congratulates Emirates Team New Zealand for winning the Louis Vuitton Cup for the second time!
Never heard of the Louis Vuitton Cup sailing race? You may have heard of the America’s Cup, the oldest active trophy in international sport. If you haven’t, the America’s Cup is a sailing race where a challenger yacht races one-to-one against the current holder of the America’s Cup. The challenger team has earns this position by winning the Louis Vuitton Cup. Continue reading
In June, I had the pleasure and privilege to present at the Tokyo ANSYS Convergence User Group meeting. Presenting highlights of the ANSYS fluid dynamics solution to more than 1,200 attendees was exhilarating! But since many of you may have attended these events, I won’t do a repeat of the presentation here. Instead, i will share my visit to the
Tokyo SkyTree tower, that city’s new TV tower. The old Tokyo Tower was too small to transmit digital TV signals, since many high rises obstructed its line of sight. Therefore, the SkyTree tower was built and measures 634 meters high, which is 301 meters higher than the old Tokyo Tower. It is also the tallest tower in the world and the second tallest structure, just behind the Burj Khalifa.
While visiting, I overheard a couple asking each other if a violent wind could sway the tower. The answer, thanks to clever architecture, is that it will not. (I could have told them this answer, but who would trust me!) How could a 650 meters thin tower not sway in the wind? The answer is in the core design. Continue reading
I had the pleasure to attend our regional user group conference, called ANSYS Convergence, in San Miguel de Allende, Mexico. The event was hosted by our partner Grupo SSC at the end of April.
As with every UGM I attend, numerous customers present their case studies, and I am always impressed by the quality of the work and how they use simulation to develop better products. If you’ve read some of my previous blogs, or attended one of my presentations, you know I always say that this is what simulation is for. The presentations from engineers using simulation, once again, reinforced my belief! You may be sitting there thinking — OK, so what’s new?
Well, this time ANSYS users took it to the next level. Not only did they show the results on a slide, they actually came to San Miguel with their products!!!!
This was tied to a special occasion: the inauguration of a new building of Instituto Sanmiguelense, which teaches engineering using ANSYS software. Clients displayed the products they are developing with the help of ANSYS simulation tools on the main floor of this new building. And WOW, was that impressive!
Mabe International showcased a washing machine and dryer, for which simulation is used to make sure there are no vibrations as the tumbler rotates.
To learn about a wide variety of topics, you may want to watch the Woody Allen movie, “Everything You Always Wanted to Know … But Were Afraid to Ask.” But if you want to know about turbulence, you’ll need to read some technical briefs authored by Florian Menter, research and development fellow at ANSYS who is a world-recognized expert in turbulence modeling.
As you probably know, the vast majority of industrial flows are turbulent, and turbulence is an extremely complex phenomena. Furthermore, industrial geometries are complex. So now you have a complex design and complex physics. To predict the behavior of turbulence, you need a tool that allows you to easily simulate all those complexities.
For example, simulation enabled engineers to determine the wind pressure and flow around the Guggenheim Museum’s facade in Bilbao, helping to facilitate the design of this landmark structure.

At the end of February, I blogged about how I had the pleasure of talking with Desktop Engineering magazine’s senior editor Kenneth Wong via podcast. He had a simple challenge for me: For a structural engineer who is just beginning to work with fluid dynamics, outline the points important to CFD flow simulation. He also asked me to explain how to avoid pitfalls when setting up the simulation and what to look for when analyzing the results.
That podcast focused on the simulation setup. More recently I met again with Kenneth, and this time he wanted information about how to run the simulation and analyze the results to extract key engineering information.
Remember, we are looking at a ball valve design. In this design, the flow pushes on the valve when it is partially open, which could deform or move the valve enough to make it leak. The analysis simulates flow behavior inside the valve to determine whether or not the valve leaks.
First we focus on how to ensure that the solution process has gone the way it should. Continue reading
One of my colleagues mentioned to me that it is National Engineering Month in Canada and that reminded of a great tradition I learned about from a dear Canadian friend — the Iron Ring.
The Iron Ring (which is actually now primarily made of stainless steel) is a ring that Canadian engineers wear on the little finger of their working (dominant) hand. The finger on which the ring is worn is crucial because as the engineer works the ring will drag on the surface where he or she is writing or moving his/her mouse. This is especially true for newly graduated engineers, whose rings have sharp, unworn facets.
Now you may wonder why would engineers wear such a ring, which is designed such that engineers can always feel its presence when they work. It seems like an awfully bad design! On the contrary! It is the perfect design for its purposes:
- A reminder of the obligations and ethics associated with their profession
- A reminder of the social significance of being an Engineer
- A reminder for experienced engineers to welcome and mentor newly-graduated engineers Continue reading
