Don't settle for Computational Fluid Dynamics (CFD) software that uses (abuses) facets 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.

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.

Yet another way to reveal the hidden secrets of your Computational Fluid Dynamics (CFD) simulation is to create a face, usually a plane and often referred to as a cutting plane, to serve as a target for interpolated results.
