2014 ANSYS Convergence Conferences — Registration Now Open

Meeting with other ANSYS software users and partners at a 2013 Convergence Conference

Meeting with other ANSYS software users and partners at a 2013 Convergence Conference

Wow, I can barely believe how time flies. We are only a month away from kicking off our first group of 2014 Regional Convergence Conferences. The first conferences begin in Poland (April 10-11), Turkey (April 18) and Austria (April 24-25) with worldwide Convergence Conferences running throughout the year (view all conference locations).

I’ve told you in the past why I love these conferences (2013 Tokyo Convergence Conference and 2013 Mexico Convergence Conference) but I will say it again. It is extremely exciting to see how engineers use ANSYS technology to develop state of the art products. It is always a very humbling experience for me to see so many great designs and products where simulation plays a key role. But that is just me — I am a geek!

Now let me tell you what I heard from attendees at the 2013 conferences and why they liked it. Continue reading

Reliable Turbomachinery Blade Development

Our Tech Tips for reliable turbomachinery blade development looks a little different this month because (unbeknownst to me) our IT department is moving some equipment this weekend, and well, I didn’t want you to miss out, so we’re cross-publishing this one on turbomachinery here on the blog!

Turbomachinery Blade Development with Aero-Mechanical Simulation

Engineers need advanced simulation tools to enable them to meet customer demands for more-efficient and reliable high-performance machines. Engineers must accurately predict aerodynamic performance across an increasingly wide range of speeds and operating conditions, and they also must guarantee reliability in the design. For example, they need to ensure that blade vibration will be damped across the operating range and that cyclic unsteady loading will not impact design life.  Continue reading

A Ferrari Inspired Olympics Bobsleigh !

The Sochi 2014 Winter Olympics are in full swing and, of course, any respected blog must talk about it! While there are many topics of great interest, I was looking for a story or achievement that may not be that obvious. Found one!

Did you know that Ferrari is racing in the Olympics? No, we will not see a Ferrari car racing in a cross country ski competition — although would be great to watch! But Ferrari is a key part of the Italian bobsleigh design team and did numerous computational fluid dynamics simulations of the bobsleigh. They studied the flow around the bobsleigh, around and between the racers, etc. The goal, of course, was to reduce the drag to ensure maximum speed on the track.  Continue reading

Behind the Scenes at ANSYS: Project Simulate a Reindeer

Dear Readers,

simulate a reindeer morph a reindeerHere I sit late at night, a couple of days before Christmas Eve, in front of my computer looking at the mesh of a reindeer that my colleague Simon Pereira just sent me. (You may be thinking — “Gilles, time for you to get a life”.)

Well, easier said than done! All of this started a week or two ago, after our dear social media manager, Sandy Adam, requested a cool simulation for our holiday blog. In a moment of complete weakness, I emailed her back saying: “Why don’t we find a good aerodynamic position for a flying reindeer?”. The response was immediate — “Thanks Gilles for volunteering!”.  I was not going down alone so I took Simon with me on this adventure!

I thought you might enjoying a behind-the-scenes view at our email conversation last week about the project. Continue reading

Could RBF-Morph Technology Help Design Submarines That Move Like Stingrays?

I just saw this really cool video about how researchers at Harvard University and the University of Buffalo looked at the stingray motion in water to think about a new design and propulsion system for submarines.

As you can see, they performed CFD simulation of the stingray motion. As soon as I saw the CFD animation I thought to myself — to do such a simulation, they need to have a good mesh morphing capability as the deformations are large. Why mesh morphing and not fast remeshing? Continue reading

Ferrari Races Ahead with CFD Simulation

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

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

ANSYS Congratulates the Emirates Team New Zealand

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
