James Clement tries to capture "the big one".One warm July morning buddy of mine and I decided that we needed to hit the lakes and go catch "the big one". We headed out just as dawn broke so we can find that big old bass that I knew was hidden somewhere in our favorite spot. Once we got the boat in the water it is about a 15 minute ride across the lake over to the spot where our fish was bound to be. So a cup of coffee in hand we sped off across the lake, during that time one’s mind always tends to wander and apparently mine wanders back to meshing. Looking across the still lake nothing much is going on but behind the boat is a whole different story; the propeller is stirring up quite a bit of turbulence and the hull is producing a massive wake, this is where the action is. So I ask to myself, what kind of tools would our users need in order to build meshes automatically in order to capture this type of phenomena? A tool that would allow efficient meshes and could give accurate answers with a minimal cells count. STAR-CCM+ v10.02 meshing operation allows users to refine wake zones in both the polyhedral and the trim meshers as well as give wake a draft angle so that the refinement zone expands as it moves away from the model.

You may have noticed that in the upcoming STAR Global Conference, there will be an inaugural Genius Competition designed by our very own Dr Mesh. Wanting to find out more about the competition myself, I recently caught up with Dr Mesh at the Paradise Point Resort and Hotel in San Diego where he was catching some New Year sunshine and inspecting the facilities for the upcoming STAR Global Conference in March. He was looking relaxed and tanned as he emerged from the blue waters of the Pacific Ocean onto the white sandy beach, stopping only to create some weird looking cell shapes from the moist white sand at the water’s edge. He pondered for a while as he gazed out over the ocean and it was a good opportunity for me to tip toe around the polyhedral sand sculptures and ask him some questions about the new STAR-CCM+ Macro competition that would be held during the conference.

It is our pleasure to announce James Bertwistle as the winner of the 2015 CD-adapco Calendar Contest. This year again, contestants from all around the world submitted images of exceptional quality. James’s entry, which represents the Wind Effects around Tall London Buildings, scooped the first prize owing to its beautiful and accurate representation of urban wind flow, as used in environmental impact assessments for new building developments during the planning application process.

James is an expert user of STAR-CCM+®, having started working at WSP nearly 10 years ago as a graduate from the University of Leeds CFD Masters course. He is now the Associate Director of WSP’s Computational Fluid Dynamics group in the UK, leading a team of CFD modeling engineers specializing in performance-based design for the built environment.

I met up with James to find out exactly how he applies simulation to real-world engineering problems.

휴스턴의 회의실이나 휴게실에서 시간을 보낼 때 대화 주제들은 곧 그 날의 유가 가격으로 바뀌게 될 것 입니다. 세계 경제 성장률 저하와 북미 Shale 가스 공급 혁명으로 유가 가격은 지난 3달동안 약 30% 하락했습니다.
제가 이 블로그에 쓴 것과 같이 서부텍사스산 중질유는 5년만에 최저가로 거래됨에 따라 업계는배럴당 70달러로 운영하는 것을 포기해야 할지를 심각하게 고민하게 되었습니다.

이러한 새로운 패러다임에 대응하려는 각 기업들의 관점이 다를 수 있지만, 대부분은 안전성을 해치지 않으면서 시간과 비용을 줄이는 노력 (혁신적이고 양질의 제품과 솔로션 납품)을 지속하려 합니다.

기업들이 점점 해석 기반의 최적화에 의존함에 따라 우리(CD-adapco)가 제공하는 엔지니어링 해석 툴들이 무엇보다도 중요한 역할을 할 것으로 생각됩니다. 이런 선도 기업들은 시뮬레이션을 통해 엔지니어링 비용 및 시간을 줄이고 있습니다.

As an engineering educator, do you wonder how to meet the needs of industry today while researching and developing technology for future generations?  As a professional, do you stay awake at night wondering if tomorrow’s engineers will be prepared for engineering success on your real-world applications?  Countries around the world are forecasting a shortage of engineers in the coming years and there is speculation today’s engineering graduates are lacking the necessary skills and abilities needed to be successful in current and future engineering environments.

How do we meet the needs of industry in the 21st century while researching and developing technology for future generations? How do we prepare tomorrow’s engineers for engineering success on real-world applications? The answer is simple: we must all work together. By “we,” I mean academia, industry and (for the purposes of this Blog) CD-adapco as an engineering tool provider.

Academia and industry have been successfully collaborating together for over 100 years. When industry and academia work together to push the boundaries, they form a powerful team capable of driving innovation and economic growth. Moving forward, there needs to be more open communication and collaboration between industry and academia to understand and address the qualities and skills engineering graduates should possess when transitioning from academia to industry. This means collaboration needs to expand from research labs and into the classroom.

Bridging the Gap Between Academia and Industry

The other day, my designing skills were put to the test. A tad too far. I was using the 3D-CAD modeler in STAR-CCM+. I mean my final design objective was nothing compared to what some of the STAR-CCM+ users are able to build: did you ever see this STAR-Bike built in 3D-CAD?!

It’s been said that education and competition are two of the most important ingredients in life. There is no doubt that education (whether it be formal or informal) is a primary key to success, and the roots of education reside in competition. Throughout your educational career, you will continuously compete and I can guarantee - it won’t stop when you graduate! Whether you are in a contest to be the fastest runner on the playground, the National Spelling Champion or up against a number of other MBAs for a plum job at a Fortune 500 company, competition will always play a part in your life.

To recognize and encourage the innovative use of our software, the CD-adapco Global Academic Program is announcing the first ever STAR-CCM+ SIMULATION APP CONTEST! Using the Simulation Assistant in STAR-CCM+, we challenge you to develop an App which captures best practices.

2D simulation is a great way to test out designs and boundary conditions, personally I use it all the time when I am setting up a complex case for the first time or just playing with a new feature.
Historically in STAR-CCM+ there wasn’t a pipelined way to build and run 2D meshes, but now with version 9.06 there are two new features that will put that problem to rest.
