Editor’s Note: As Thanksgiving approaches, we’re happy to share one engineer’s quest to cook the perfect turkey with the help of computational fluid analysis (CFD). Have a happy Thanksgiving.
As the annual Thanksgiving feast approached at our house (and my wife isn’t, let’s say, experienced at cooking American food), taking the engineer’s perspective, I decided I would prefer not to have hit or miss Thanksgiving holiday dinners for the next 10 years while figuring out what is important and what isn’t when it comes to roasting a turkey. I had some empirical (experimental) results from the last two Thanksgiving dinners, but not enough to make my conclusions, so I built a computational fluid dynamics model in the Mentor Graphics FloEFD software and ran a number of airflow analyses to answer some of the questions that were plaguing me. Just exactly what is the best way to cook a large turkey, what effect does the type of oven have, and what type of rack and roasting pan produces the best results? In this article, I discuss the details of the model and my analyses, providing answers to these age-old mysterious questions once and for all. Continue reading
At $0 to $49 per user per month, GrabCAD Workbench, a cloud-hosted collaboration and file-sharing service, must have sounded like April Fools’ joke to some, but it was not. Since it came online in April, the product has picked up 15,000 users. Last week, GrabCAD decided to boost its functionality with added features to join the desktop and the cloud repository.

Dassault Systemes 3D Experience Forum 2013: “Taking the Cloud Back to the Enterprise, Not the Other Way Around.”
It’s an interesting exercise to study the evolving vocabulary at tech conference keynotes. About five or six years ago, speakers went out of their way to hail PLM. Today many prefer to keep PLM references to a minimum. Instead, they pepper their talks with “social,” “community,” “apps,” and “cloud.” It’s a reflection of tech consumers’ changing attitude. They want easily deployable, social media-inspired solutions with an always-on connection to the web and a cancel-anytime option. Continue reading
This week’s Siemens PLM Software NX CAE Symposium 2013 at the University of Cincinnati featured more than two dozen presentations, roundtables, and panel discussions, as well as two workshop tracks. Siemens PLM Software NX customers explained how they used the software to simulate everything from tiny 0.015mm cardiovascular stents to huge, ship-based cranes and heavy-lift rockets. While the simulation projects were varied, there was a common theme running throughout the symposium: the need to reduce cycle times via collaboration and system-level engineering. Continue reading
