My involvement in the World Cup is a little more personal since my first project at CD-adapco involved the aerodynamics of soccer balls. The 2010 World Cup ball, the Adidas Jabulani, had its fair share of criticism due to its shallower seams and 8-panel design leading to erratic flight paths. The ball was difficult to control for the players and rumors have it that some goalkeepers still have recurring nightmares of the ball. In 2010, CD-adapco teamed up with Wilson Sporting Goods to study the aerodynamic behavior of soccer balls and the impact of the newer panel designs.

Advanced Simulation for Electric Machine Design
Electric machines are ubiquitous across our everyday life - from automotive to domestic appliances, aerospace to industrial usage - these machines are the workhorse of industry and modern amenities. New regulatory efficiency requirements, fluctuating costs of permanent magnets, and the ever present goal of higher performance from a smaller package, increases pressure on both the design and optimization of electric machines across all applications. This webcast explores the many techniques used to predict electric machine performance, including analytic models, lumped parameter models based on...
I am not a soccer fan, but all the men in my life are fanatics and thus World Cup fever has taken over the Goodwin household. You might be surprised at what happens when an uninterested CFD engineer is forced to watch soccer...
Dancing Dice with Overset, DFBI and Contact Coupling
CFD simulation of dice roll in STAR-CCM+ v9.04 using Overset, DFBI and Contact Coupling.
During the opening session of the STAR Global Conference earlier this year, Didier Halbronn, CD-adapco Vice President of European Sales, spoke about our ongoing commitment in the field of multi-disciplinary design exploration (MDX). In this blog I want to highlight a couple of new features in v9.04 of STAR-CCM+ that approach this in different ways.
In an effort to make STAR-CCM+ even faster on a broader range of problem types STAR-CCM+ v9.04 (which is released next week) will offer Concurrent Per-Part Meshing (which is a bit of a mouth full, so we'll call it CCPM instead). Now, I'm sure you're asking yourself, ‘What’s the difference between CPPM and regular parallel meshing?’
With the release of STAR-CCM+® v9.04 customers will see reductions in overall time-to-solution and dramatic gains in productivity using STAR-CCM+ v9.04 workflow improvements, parallel meshing and optimization capabilities. The addition of new physics models allows users to perform increasingly realistic CFD and CAE simulations, that more closely represent the real world conditions under which the product will operate.
