June 2014: World Cup Edition

This month's articles take you from the meshing world cup to the actual World Cup. The 23rd International Meshing Roundtable is running a mesh competition (the nearest thing the mesh world has to a world cup) based on London's Tower bridge, so see if you think Caedium Professional has what it takes to be a contender. Then there's the actual World Cup and, if aerodynamics is your thing, all that matters is the ball.

Tower Bridge Meets CFD

Complete, watertight, complex geometry is a rare but welcome find in Computational Fluid Dynamics (CFD). However, thanks to the steering committee of the upcoming 23rd International Meshing Roundtable, such a geometry, in various formats, is freely available for their meshing contest. The star of the contest is London's Tower Bridge, I presume in honor of the conference's host city. So to the bat cave to see what Caedium Professional can do with this model. Read more >>

World Cup Balls

Every 4 years the FIFA World Cup rolls around and the question on everyone's lips is...how will the official match balls behave? Oh, and to a lesser degree, which nation will win?  Ball aerodynamics are complex, but relatively well understood. Given the typical speed and spin of balls in the beautiful game, small changes to their surface texture (the focus of much recent effort in ball design) can have dramatic repercussions on their trajectories and hang times. Balls are deemed so important that each has its own Wikipedia page and each has tournament-flavored names thanks to Adidas, the long time ball designer. Read more >>
