Beth, right after the SIM Center moved from Mississippi State to UT Chattanooga, the Center arranged an open house for engineers interested in learning more about CFD. I went. The prospect of combining fluid dynamics with CAE really fascinated me. I was blown away by the capability of the software and the modeling techniques. The first demonstration used a tractor/trailer combination and modeling air flow around the cab and trailer at various speeds. The second model demonstrated air flow around an F- 18 Hornet and how that air flow varied when airfoil surfaces came into play. The graphics were absolutely stunning. One thing I came away with was the close correlration between model and reality. In the "old days", reality was hard to come by due to issues with the mathematical algorithm. An approximation within 25% was considered to be "state-of-the-art". Times have really changed.
Thanks for the added detail, Bob. You're absolutely right about the challenge of modeling to reality, however. While your 25% percent approximation figure has been greatly improved with the latest technology, it's still one of the challenges around CFD and simulation in general.
NASCAR is one of the most interesting "playgrounds" for engineering and cutting edge tools. Before I became a NASCAR fan, I thought they just got a showroom car and put a huge motor in it. Oh no, so much more! Design of roll cages and frames for driver safety, spring rates and shock response under varying conditions, engine building and tuning, aerodynamics. etc. F1 racing seems to have more electronic control over various parameters while the car is on the racetrack, while also using engineering applications in the design and test phases. A lot of engineers have found their "happy place" in the world of motorsports.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
