TechTalk: A real-life case study about CFD in the Autodesk 360 Cloud

Autodesk entered a partnership with the uberCloud experiment over a year ago. It was an interesting opportunity to get out in front of a community of engineers, scientists and early adopters who are interested in leveraging the cloud for computation. The experiences and backgrounds of the community are vast. Some have been involved in heavy HPC applications for many years, some were design engineers that had alot of design alternatives floating around in the minds, but didn’t have the time or resources to explore the possibilities.

Our team partnered with Mark Lobo at Lobo Engineering to explore a real world application of maximizing flow and pressure drop through a valve assembly. Mark was able to run over 200 simulations and take the work that typically would take a month, down to a day.

Join us next week as Mark shares his experiences of life as a CFD Engineer leveraging the cloud.

The World Cup Simulated

The world is revving up for an exciting month of “futbol” (soccer) with the official kickoff of the World Cup in Brazil. Interestingly enough, we’ve done a bit of simulation work around aerodynamics of different ball designs. I did a bit of digging and found an image from a recent project. Below is a CFD simulation of a soccer ball spinning through the air. The goal of the simulation was to look at different surface conditions and compare different speeds and rotations. We also looked at a variety of stitch patterns. Similar to a golf ball, the surface of the ball has a big influence on how it travels through the air. Of course, for most of us, it probably doesn’t matter. But, when you are dealing with the best of the best, every little bit matters. upfront CFD & World Cup What appears to be a fairly kick of a ball can turn into quite a sophisticated simulation application. Depending on how far into the multiphysics aspect of the problem you want to go, you could easily find yourself dealing with nonlinear materials, impact, effects of deflection of the ball with initial flight trajectory as well as the aforementioned airflow characteristics. As with all thigs, I guess it depends on what exactly you are trying to learn and improve. In the spirit of #simulationfriday, I figured I’d share this fun example. Have a great weekend.

The Power of Visualization in CAE Simulation

The end result in any CAE Simulation revolves around conveying our results graphically. Whether it be a 2D graph or a high fidelity 3D visual image. Historically, in Simulation, we tend to be on the conservative side as we are focused on accuracy and the integrity of the results. But, wondering – should we push for higher fidelity realism in our visualization tools. Is there a place for it?

Check out the below video using Autodesk Simulation CFD and VRED.

The interesting thing is when I show this sort of thing to customers they seem to love it. But, to be honest, the results presentations I have sat through over the years are far from inspiring.

So, the question on this fun #SimulationFriday heading into summer. How important is it to have realistic visualization for simulation at your finger tips? Would it help you broaden the acceptance and “stickiness” of simulation within your organization? Are we content with the days of simple 2D plots and graphs? How about mobile, are we using phones and tablets to present results? Curious to hear what people think?
