Winter is coming to the Northern Hemisphere and, with it, lots of travelling for Thanksgiving and the holidays. Did you ever notice that upon traveling you sometimes end up getting sick afterwards? Ever wonder why? Researchers at the FAA Center of Excellence at Purdue University, created this simulation of a sneezing passenger using ANSYS to study the mechanics of pathogen travel in airplane cabins.

Lets talk combustion simulation. I know you dear readers, you are smart! So I will not bore you with explaining what combustion is. Rather, I want to give you some fun facts. As you will see, combustion is really everywhere. Continue reading
I am excited to go to Colorado at the end of May…and it is not because of what you have been reading in the news! It is because I am excited to attend the NAFEMS 2014 America’s Conference that will be held May 28th-30th in Colorado Springs, CO.
First, what is NAFEMS. NAFEMS is a non-profit that was created in 1983 in the UK by the National Engineering Laboratory. The acronym stands for “National Agency for Finite Element Methods and Standards”. But it grew from there and is now referred as the International Association of the Engineering Modelling, Analysis and Simulation Community (from nafems.org). It is a very important organization for simulation and the dynamism of the simulation industry. It provides training in simulation, helps establishing simulation best practices, is an advocate for simulation deployment, etc. Continue reading
This Sunday is Mother’s Day in the U.S. and over 50 other countries around the World. If you forgot or are not sure if it’s this weekend for you, here is list of Mother’s Day dates.
Of course, the person I will think about is my mother, and I while could easily write a blog about her, I am a private person and thought I would instead share with you some stories of other amazing mothers! Continue reading
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
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
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
Here 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
