I ran across an article the other day that made me, ahem... perk up. CFD was used to simulate roasting coffee beans! Coffee is something I know AND care about. But why would CFD be needed for something as "non-techie" as roasting beans? Like everything else under the sun, it comes down to plain ol' chemistry. The final flavor profile of the bean will vary widely based on temperature and roast time.

I spent most of my career in industry running free, open source CFD tools and it was not until I started using STAR-CCM+®  a few years back that it finally dawned on me : free simulation software often comes with a hefty price tag. I understand that this may sound like a contradiction in terms, after all it doesn’t get any cheaper than downloading a code with one click of a mouse and having the freedom to use, modify and share it without spending a dime. But there is a far- reaching hidden cost that must be factored in when considering the true value of your simulation software: your time spent making it work. And how much is that time worth?

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.

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...

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?’

...you can't beat the gas mileage!

It all started in 1982 when Hans Tholstrup and Larry Perkins built a solar-powered car and drove it across the entire continent of Australia. Driven by the success of their vehicle, aptly named "Quiet Achiever", they encouraged others to push the limits of alternative energy vehicles. Five years later, the very first World Solar Challenge was born. Every other year since, teams from across the globe - prominent universities and private organizations alike - converge in Darwin, Australia to make the 3.000 km trek south to Adelaide in their solar-powered vehicles using regular ol' public roads and minimal camping gear for the seven-day journey.

CD-adapcoで働いていると、もうすぐリリースされるSTAR-CCM+の刺激的な機能を解説したたくさんのクールなアニメーションを見ることができるという良いことが体験できます。新機能がリリースされるまでこれを皆さんと共有することができないのはフラストレーションが溜まります。今日、私自身何度も見返している、お気に入りの2つビデオをご覧頂くことに、私は非常にワクワクしています。
これらのビデオはSTAR-CCM+ v9.04のDFBI(Dynamic Fluid Body Interaction)ソルバーの新しい接触モデルを説明しており、移動物体と壁面間の接触/衝突の直接のモデル化を可能としています。

私たちの多くは、STAR-CCM+のGUIの前で長時間過ごし(あるいは長時間のように感じてしまう)、そしてふと、「どうやったらもっと簡単にできるのかな?」と心に疑問が生じます。 なんだかんだ言っても結局のところエンジニアの私たちは、エレガントなソリューションを発見することをほぼ強制され、多大な時間を必要とするソフトウェアとのやりとりを削減するための機会に飛びつくことになるでしょう。 幸運にもSTAR-CCM+ v9.04には、あなたの人生をより容易にするために設計された、さまざまな範囲の時間節約機能が搭載されています。

Although researchers claim to have cracked the formula for a supersonic car (SSC) capable of reaching a record speed of 1000 mph (1600 kmph) and the ability to cope with the aerodynamic characteristics of travelling that fast, I am here to say… “Meh - been there, done that!”

Unfortunately, there has been some debate regarding the veracity of my 1000 mph VW Beetle. Therefore, I am widening the audience to ensure that proper analysis of the photographic evidence can ensue...
