"We used Exa’s PowerFLOW transient solver that directly resolves very large eddies to deliver superior accuracy compared to conventional CFD codes. This approach is especially beneficial in areas where flow physics are complex such as in the rear of a curved vehicle. The result is a full-size electric sedan with a drag coefficient of 0.24.

"We are raising the bar with full-scale simulations....The simulations of the full-scale aircraft with noise reduction concepts will help recover a significant part of the loss of the flight test. In addition, the simulations provide valuable insights into the sources of airframe noise.

シミュレーション主導の製品開発

 

弊社はシミュレーション主導の設計開発を行うソフトウェア製品ならびにコンサルティングを提供しております。主要メーカーでは、弊社の流体、熱伝達および流体騒音シミュレーションソリューションを活用し、製品性能の最適化、開発コストの削減、さらに設計とエンジニアリングプロセスの効率を改善しております。

 

シミュレーション主導の設計は、設計初期における製品性能の予測を可能にし、後期で発生する設計変更や試作および実験にかかるコストの削減を実現します。また、弊社のソリューションは、設計と解析間でのイタレーションスピードを促進します。これらの特長により、潜在的な設計バリエーションが、想定される性能領域に対してどのような影響を与えるかについての貴重な洞察を得ることができます。さらに競合するデザインと設計上の制約や要求の間におけるトレードオフを最適化するソリューションを見いだすことができます。

 

"The slightest shift in the curve of the headlights, the shape of the fender, or the angle of the mirrors can dramatically alter a truck's business value. Take that mudflap, for example: A little haircut added an extra half-percent of fuel efficiency to the T660. It is one of several tweaks that could save a 1,000-truck fleet $1 million a year. "

CFD development of the Jaguar XE

 

Due to be launched in 2015, the aerodynamic package for the Jaguar XE was designed in CFD using software supplied by Exa. Its sleek profile has the lowest drag coefficient of any Jaguar yet

 

 

Congratulations Renault on your EOLAB concept car!

 

Exa PowerFLOW was used extensively in the aerodynamic development of this brilliant 282 mpg, lightweight supermini of the future.
