In Brookings, South Dakota, a town of about 19,000 people, big things are happening; things that touch millions of people in nearly 100 countries, from Liechtenstein to China to Brunei. Bob Cramblitt tells how small-town Daktronics is using upfront CFD to light up the world.
Believe it or not, computational fluid dynamics (CFD) has been around longer than computers. In the early 20th century, researchers were applying numerical approximations to partial differentiation equations (PDEs) and solving them with mechanical calculators. Rita Schnipke, chief technology officer of CFdesign, shares her personal history with CFD meshing.

Meshing is the Achilles heel for both new and experienced users of CFD. But Luke Mihelcic maintains you don’t have to get meshed up about meshing. He offers four tips for creating a better mesh.

Jim Spann asks: If you came to work this morning and found your PC replaced with a typewriter how would you react? Or for those of you who need to do more than just word processing, how long would it take to re-start your heart if your boss handed you a deck of old-school computer punch cards and told you to get to work?
An expert look at FE meshing
One of the initial steps in performing a CFD analysis is to mesh the geometry. So, what is a finite element mesh all about? Why do we need it? What does it do? Rita Schnipke, CTO of Blue Ridge Numerics, gives a primer on finite element meshing.
