Symmetry is a simple but powerful concept that you can use to speed up your Computational Fluid Dynamics (CFD) simulations and reduce your memory requirements. Join me in an exploration of a simple symmetry case.

Pareto analysis usually reveals a golden 80-20 rule for squeezing performance out of things. In other words - it means the majority of the performance (80%) is typically governed by a minority (20%) of factors. Pareto analysis applies equally across many disciplines from sports (marginal gains anyone?) to product design.

Don't settle for Computational Fluid Dynamics (CFD) software that uses (abuses) facets (e.g., STL) as geometry. If your original geometry is analytic (CAD) then mesh it directly without the conversion to facets. Otherwise it's like you have to create two surface meshes. What's wrong with that? Plenty!

The spectacle that is the Tour de France (TdF) is all about aerodynamics - and you thought it was all about the bike. Virtually all tactics in the TdF are dictated by individuals or teams of riders attempting to limit their exposure to the 'wind', in order to minimize drag and therefore minimize the effort required to progress. There are some obvious and not so obvious tactics riders and teams employ to use aerodynamics to gain advantage.

Had any wacky/extreme/unusual/innovative/interesting/off-the-wall fluid dynamics design ideas recently? Then let Computational Fluid Dynamics (CFD) guide you through the impossible until only the best remain, no matter how wacky.

News just in from Bloomberg is that Larry Page, of Google fame, is funding not one (Zee.Aero) but two (Kitty Hawk) personalized flying-machine (dare I say flying cars?) startups. With a number of other companies pursuing the same goal, it seems a gold rush of sorts is on. Yet remember the real gold rush? The real benefactors were the pick and shovel makers. The equivalent in this flight to the future are employees with highly prized skills brought to bear on a decidedly tricky problem. And at the sharp end of those with specialized skills are...Computational Fluid Dynamics (CFD) experts - providing valuable insights into aerodynamics, propulsion, batteries, and electrical/electronics cooling.
