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
Google Docs brought us word-processing in the cloud. Adobe Creative Cloud is pushing us toward photo-editing in the cloud. Dropbox taught us to manage files and folders in the cloud. It’s inevitable, then, that sooner or later simulation would head to the cloud.
Most computer-aided engineering (CAE) software vendors are bidding their time, observing the trend on the sideline. They support private cloud — dedicated servers installed at clients’ sites to run simulation — but are reluctant to dive into the public cloud. That’s understandable. Their codes and licensing practices are driven, for the most part, by users devoted to desktop workstations and clusters. Continue reading
The conversation began months ago when I posted a motion for discussion in the LinkedIn group called “New Trends in CAE Simulation.” I asked, “Do you agree or disagree? It’s dangerous to simplify FEA and make it accessible for the masses.”
There’s clearly a push among computer-aided design (CAE) software vendors to package their simulation programs for a broader audience. These programs have historically been the domain of Ph.D.-level experts. Some critics see the move to reinvent them for designers and engineers as “dumbing down” a complex process. Others believe greater accessibility to simulation through simpler interfaces would lead to better designs. Continue reading
Altair Engineering, best known for its simulation software, is rolling out a major release of its flagship suite, HyperWorks. The comprehensive lineup covers every phase of design development and testing, from computational fluid dynamics (CFD, with AcuSolve), crash analysis (HyperCrash), sheet metal form (HyperForm), and meshing (HyperMesh), to structural analysis (OptiStruct), and more. The latest upgrade, HyperWorks 12.0, emphasizes the growing importance of composite materials, optimization, and collaboration. Continue reading
