I think I figured it out. The Patriots might be using real-time CFD simulation to raise their field goal percentages.
As anyone who watches the NFL knows, the Patriots are perennial winners. With their third Super Bowl appearance in the last four years, it seems they have an automatic ticket to the big game. However, all six of their appearances in the last 14 years have been close, coming down to 4 or fewer points. A single missed field goal could have sent the Lombardi trophy to a different team.
Fortunately for the Patriots, their kicking game is top notch. New England has finished in the top 5 in made field goal percentage in 4 of the last 5 years, with a league best 94.6% made field goals in 2014. Is this because they only attempt conservative kicks, or play in a closed stadium? In fact, it is quite the opposite. Continue reading
A few days ago someone asked me if ANSYS flagship products are appropriate for the “average” engineer, and more particularly design engineers doing upfront simulation. I believe the better question to ask is which ANSYS products are geared toward design engineers, and why.
More often than not, design engineers are quite familiar with 3-D modeling tools, which are the starting point of simulations in the product development process. But given their focus on product design, manufacturability, documentation, etc., they typically do not have time or prior experience required to learn how to use a fully featured simulation tool like ANSYS Mechanical or CFD.

Since its creation, hang gliding has progressed solely — and often painfully — through experimentation. But engineering simulation is starting to change that.
The German inventor and flight pioneer Otto Lilienthal made over 2,000 flights as long as 820 feet in gliders he designed and flew in the 1890s. He died in 1896 from injuries sustained in a glider crash, but his well-documented accounts of theories and experiences with flight influenced many of the early aviation pioneers, including the Wright Brothers.

Turbomachinery can be the most rewarding of CFD simulations. At the same time, it can be the most challenging.
Turbomachinery covers a broad range of products including compressors, turbines (gas, hydraulic, steam, wind), turbochargers, pumps, fans and more. And turbomachinery users demand ongoing improvements, such as increased efficiency, reliability and durability while reducing emissions (for those involving combustion) and noise. Continue reading
