http://www.symscape.com/blog/symmetry-to-the-rescue
<p>Symmetry is a simple but powerful concept that you can use to speed up your <a href="http://www.symscape.com/computational-fluid-dynamics">Computational Fluid Dynamics (CFD)</a> simulations and reduce your memory requirements. Join me in an exploration of a simple symmetry case.</p>

http://www.symscape.com/blog/in-search-of-the-remaining-20-in-the-pareto-80-20-rule
<p><a href="https://en.wikipedia.org/wiki/Pareto_analysis">Pareto analysis</a> 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 (<a href="http://www.bbc.com/news/magazine-34247629">marginal gains anyone?</a>) to product design.</p>

http://www.symscape.com/blog/never-settle-for-facets
<p>Don't settle for <a href="http://www.symscape.com/computational-fluid-dynamics">Computational Fluid Dynamics (CFD)</a> 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!</p>

http://www.symscape.com/blog/when-good-cfd-goes-bad
<p>You've <a href="http://www.symscape.com/node/1166">checked everything</a>, and I mean everything, but still your <a href="http://www.symscape.com/computational-fluid-dynamics">Computational Fluid Dynamics (CFD)</a> simulation does not resemble reality. Then it's time to consider the deeper underlying basis of your CFD software.</p>

http://www.symscape.com/blog/how-aerodynamics-dominates-the-tour-de-france
<p>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.</p>

http://www.symscape.com/blog/go-full-circle-with-cfd
<p>There is a certain circular symmetry to the process by which you can perform <a href="http://www.symscape.com/computational-fluid-dynamics">Computational Fluid Dynamics (CFD)</a> simulations on a computer, which is also due in part to CFD.</p>

http://www.symscape.com/blog/cfd-expertise-your-modern-day-pick-and-shovel
<p>News just in from <a href="http://www.bloomberg.com/news/articles/2016-06-09/welcome-to-larry-page-s-secret-flying-car-factories">Bloomberg</a> is that Larry Page, of Google fame, is funding not one (<a href="http://www.zee.aero/">Zee.Aero</a>) 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 <em>flight to the future</em> 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...<a href="http://www.symscape.com/computational-fluid-dynamics">Computational Fluid Dynamics (CFD)</a> experts - providing valuable insights into aerodynamics, propulsion, batteries, and electrical/electronics cooling. </p>
