John Parry It was very interesting to read this article about the work IBM are undertaking together with École Polytechnique Fédérale de Lausanne (EPFL) and the Swiss Federal Institute of Technology Zurich (ETH) on a 3D stacked architecture for multiple cores. The four year collaborative project, called CMOSAIC, promises to deliver an interconnection density from 100 to 10,000 connections per square millimetre … Read More

John Parry Some people think that because Concurrent CFD is so easy to use it must be simplistic. Nothing could be further from the truth. FloEFD has some very sophisticated physical models for cavitation, combustion, etc. plus by being CAD-embedded it’s also easy to use the CFD results to drive other simulation packages within the MCAD environment. Not limited to upfront design, Concurrent CFD can be used continuously … Read More

Champcar Exhaust Analysis

Posted by John Parry

John Parry Using CAD-embedded CFD upfront and throughout the design process is the only way to go when it comes to compressing design schedules. We call this approach Concurrent CFD, as the CFD analysis can be done concurrently with design changes, taking upfront CFD to the next level. The product’s performance can be checked at each design iteration, leading to a more fluent CFD process that gives increased confidence … Read More

John Parry Some more thoughts on the fluent design vs. laminar flow analogy In my last post I used the example of an airfoil to illustrate a product design (object) that passes smoothly, or fluently through the design process (a fluid) without causing much turbulence (design rework) that otherwise disrupts the downstream flow (late in the design process) making the flow take longer to recover (increasing the … Read More

John Parry Electrical engineers often talk about a ‘design flow’, which Wikipedia defines as ‘the explicit combination of electronic design automation tools to accomplish the design of an integrated circuit.’ I heard the term a lot when making presentations at the Solutions Expos in the last few weeks. To someone with a background in fluid dynamics, flow means something rather different, but what electronic engineers … Read More

John Parry One of the things I’m responsible for in the Mechanical Analysis Division is promoting the use of our software in education. It’s something I care passionately about and see great potential for our mechanical CAD-embedded tools to revolutionize the way fluid dynamics is taught, particularly at undergraduate level. In part it’s because I believe that if engineers knew what CFD can do in terms of providing … Read More

John Parry I thought I’d put up a brief post about an exciting series of free web seminars that address key engineering challenges in product design. The first of these is a seminar aimed at engineering managers to explain how their mechanical designers can perform a CFD Analysis without leaving the familiar comfort of their MCAD tool. Web Seminar: CFD Analysis for MCAD Designers - Better Products, Faster Historically … Read More

John Parry Just had a weeks activity holiday at Center Parcs here in the UK with my two boys, aged 13 and 16, so I’m now back at work for a well-earned rest! We managed to cram in quite a lot – archery, tennis, racquetball, laser clay shooting, American pool, snooker, and kayaking, as well as a quad bike trek through the woods. Center Parcs is set in 400 acres of forest with lots of very tame wildlife, like … Read More

John Parry Strictly speaking that’s mechanical engineers, and the information comes from Parametric Design Corporation (PTC), in their white paper Five Things You Should Know About 3D CAD Software. As PTC say - it’s a startling fact. Having had experience of keeping track of my own time to charge to different projects the figure really jumped out at me. I found that if you take away the time spent on internal … Read More

It’s Magic

Posted by Nazita Saye

Nazita Saye Any sufficiently advanced technology is indistinguishable from magic. Arthur C. Clark I’ve often called mechanical engineers magicians because whenever I listen to them speak about what they do the only thing that comes to mind is magic. Much like the first time I looked at Engineering Fluid Dynamics (EFD). EFD is a different breed of computational fluid dynamics (CFD) software. EFD shares the same … Read More

Fluid Dynamics and BBQs

Posted by John Parry

John Parry Smokin’ A few years back I built a brick BBQ just beyond the end of my patio. The idea in positioning it was to be able to look down the garden when cooking, but also be able to talk to friends on the patio. Strictly speaking it’s an Australian style BBQ, so I guess I should call it a barbie It has a brick built base, so I spent some time thinking about where to site it as its not exactly moveable. … Read More

Show Me the Money

Posted by Nazita Saye

Nazita Saye Cuba Gooding Jr’s conversation with Tom Cruise in Jerry McGuire became the mantra of a whole generation. Show _me_ the money. Your manager no doubt says the same thing to you all the time but in different guises: Can we improve product performance/functionality? Can we reduce the cost of producing this product? Can we cut the budget without sacrificing quality? And let’s not forget … Read More

The Lights... they're so beautiful

Posted by Nazita Saye

Nazita Saye For some reason, the powers that be have decided to do roadworks on every major road leading out of my area of  London. That means traffic has been diverted to two minor roads. Fair enough as the leaking Victorian water pipes need to be replaced. But what I don’t understand is why they all have to be done at the same time and the same exact section of the A4 that was dug up for the entire length … Read More

Just the facts...

Posted by Nazita Saye

Nazita Saye A while ago I heard something that made me tilt my head to the side… similar to that iconic image of Nipper, the Jack Russell terrier, listening to his master’s voice on a phonograph (I was going to post the image but international copyright rules are rather complicated. If you really want to see the image, then please go to http://en.wikipedia.org/wiki/Nipper). Anyway, someone jokingly referred to … Read More
