Growing up (30 years or so ago now), shopping for weekly groceries was nothing like it is today. I was born and raised in a small village outside London and getting food for the week meant visiting many different shops, the butchers for our meat, green-grocers for vegetables and so on. Now I have my own family and I do all my shopping in one place: the supermarket. At this one large store I can get my vegetables, meat, household items and even electronics and clothing.

In the upcoming release of STAR-CCM+, v10.04, we have added two new features to significantly increase the flexibility of the CAD-clients as well as add a new dimension to the transfer. CAD-clients now allow import of reference planes and coordinate systems. These entities may be used within STAR-CCM+ for a range of tasks. CAD-clients now enables direct import of CAD files as well, opening the door to insert a bi-directional link into a template or existing sim file without the need to fire up your CAD package.

With the release of STAR-CCM+ v10.04, we are providing a powerful, and unique, new feature that will allow you to gain greater understanding of your flow and thermal analyses. For the first time, you will be able to use the adjoint solver to look at sensitivities not only within your fluid domain but your solid also. By taking account of more of the physics in your sensitivities, you can now use adjoint to help provide a better optimized design, earlier in the product development process thus reducing the risk of failures and costly product recalls.

In the upcoming release of STAR-CCM+ v10.04, we have implemented a new equilibrium motion type for DFBI bodies is used for simulating the motion of moving bodies that tend towards a steady state equilibrium position. With this feature the body is incrementally ‘teleported’ to the current best estimate of the equilibrium position rather than allowing it to oscillate freely about it.

Just weeks after announcing that we had broken a “world record” by scaling STAR-CCM+ across 55,000 cores on the 1.045 PetaFLOP Hermit cluster, we are pleased to announce that we’ve smashed it already, by scaling up to 102,000 cores on NCSA’s Blue Waters supercomputer, which included running a 1 billion cell aerodynamics simulation. Blue Waters is one of the most powerful supercomputers in the world*, and is the fastest supercomputer on a university campus.

Of course, lots of CFD vendors have claimed a “world record” from time to time. And I’m sure someone will break it again soon. But what does any of this mean in the real world? How does it help you as an engineer?

We know a good scientific visualization when we see one – colormaps are a big part of this and when used effectively, they can make all the difference. The ability to create your own colormap within STAR-CCM+Ⓡ has been around for a long time and around this time last year, we delivered a full featured interactive colormap editor with the v9.04 release.

Still, what makes for a good colormap is not common knowledge. Surprisingly, the most frequently used colormap for scientific visualization, the rainbow colormap, is regarded as one of the least effective.

In this blog I'll tell you how to choose the most effective colormap for you application, allowing you to present your results in a more attractive, more informative way.

Prometheus (which literally means "forethought"), was a Titan whom Zeus had defeated. He was given a task to go to earth and make its creatures. He crafted human beings and gave them arts and culture. But they were suffering and terribly shivering in the cold. So against Zeus’ direct wishes, he also gave “fire“ to mankind. Little did humans know that this gift meant literally they would have to “play with fire”. In order to have control over the the wild rage, as wise as they were, humans started to investigate it in more scientific ways. But they found it wasn’t very easy. In fact it was so complicated, even schoolbook combustion examples would have stiff and difficult to solve ODE systems…

Getting All Fired Up About DARS!

You might have noticed our recent announcement that STAR-CCM+® has “maintained perfect scalability” across 55,000 cores on the 1.045 PetaFLOPS Hermit cluster, at the High Performance Computing Cluster Stuttgart (HLRS). This announcement made me smile for two reasons. The first was that one of our competitors has recently been bragging about running a simulation on 10,000 cores. Well done for that! But, more importantly, because I’ve spent a lot of time recently interviewing the founders of our company for an article that I’ve written about our 35th Anniversary. One of the recurring themes in those interviews was that of computing that they had access to in the early days of the company. adapco’s first computer was a VAX 11/750, described by Steve MacDonald as being “about the size of a washing machine.” This computer, which cost a cool $200k (adjusted for inflation), was capable of performing a massive 120,000 floating point operations per second.

How does that compare to modern computers? Or even the phone in your pocket?

And so with anticipation, I opened an email from my German colleague, Nicole Vasold, with the words ‘bottle’ and ‘wine’ in the subject line. Maybe she wanted to send me a note about a very belated Christmas gift coming my way? My excitement however turned to horror when I realized the email was all work and no play, or should I say ‘All glass and no wine’? She had shared her latest work on simulating the glass coating process of a wine glass, another addition to the growing use of simulation in the glass manufacturing industry.

One of the key technical challenges facing those of us involved in engineering simulation in the oil and gas industry is multiphase flow. In every part of the production process, from extraction to refinery, we typically have to account for the combined influence of gases, liquids and solids.

The release of STAR-CCM+ 10.02 in March 2015 offers a number of new modeling approaches that could transform the way in which engineers in the oil and gas industry are able to deliver simulation results for the many problems that involve multiphase flow.
