Earthquake Weather and Other Myths

Posted by Nazita Saye

Nazita Saye I grew up in Southern California where the threat of the big one is always there – by the big one I mean the big San Andreas fault earthquake which according to experts the world over is overdue by many decades. Over the weekend San Francisco got a couple of tremblers … nothing too scary but enough to remind all Californians that the big one is lurking out there. Alas so far science has … Read More

Nazita Saye

For the past few months I’ve been working behind the scenes on a very exciting project. I’ve been working with the good folks at the Aberdeen Group, a leading Product Lifecycle Management (PLM) industry consulting and research organization, to better understand the ROI of using simulation — specifically CFD. Of course as a leading developer of CFD software we inherently understand the value of

One Hundredth of a Second

Posted by Nazita Saye

Nazita Saye There aren’t that many things in our daily lives that are measured in tenths or even hundredths of a second but athletes are constantly battling time. Sometimes a race is won with such a large margin that seconds just don’t matter (did anyone see the last few legs of the Tour de France?).  And sometimes, every nanosecond counts. If you watched the snow sports in the 2010 Winter Olympics then you’d know … Read More

John Parry So, after three blog posts, what is the moral of this Blue Ridge Numerics’ “CFD Comparison Chart” saga? Well, clearly one should not believe every “CFD Comparison Chart”! – or even the many “charts” that one vendor has put out. Rather, the story suggests that people who are thinking of buying a CFD tool for the first time might be well advised to be wary of what vendors claim about their own software … Read More

John Parry In my earlier posts I pointed out some glaring errors in the “CFD Comparison Chart” that Blue Ridge Numerics released on March 19th this year. Once we became aware of the “Chart” we quickly wrote a letter to Ed Williams, the CEO of Blue Ridge Numerics, and asked that they reveal the technical workings behind their outrageous claims. Including those I’ve mentioned, we pointed out a total of 6 very obvious … Read More

John Parry In my last post I pointed out a very obvious mistake in Blue Ridge Numerics’ “CFD Comparison Chart” of March 19th this year, which incorrectly stated that FloEFD can only handle incompressible sub-sonic flows. The reason I highlighted this as the most obvious mistake in the “CFD Comparison Chart” is that FloEFD can trace its history back to the Russian Aerospace Industry in the late 1980s originating … Read More

John Parry Rarely do I get a feeling of déjà vu in my professional life, but in March of this year something I was shown gave me a flashback to the 1980s. Some people will remember those halcyon days of two decades ago when commercial CFD was still in its infancy. Way back then the big commercial CFD vendors (Fluent, CHAM, Fidap, Flomerics, STAR-CD, and AEA) would regularly bring out CFD Comparison Charts comparing … Read More

John Parry If you’re involved in CFD in education in any way this will be of interest to you. Since shortly after Flomerics were acquired by Mentor Graphics we’ve been working towards getting out products into Mentor’s Higher Education Program (HEP), and we’ve finally got it done. To my knowledge, the availability of potentially millions of dollars worth of commercial CFD software, plus support and training, … Read More

Nearly Back to Business as Usual

Posted by John Parry

John Parry I’ve not posted for a while, which is rather remiss of me. I underestimated the response we would get to our Heatsink 201 webinar, which I gather was our most popular ever, and the number of questions that people would ask. I had around 120 questions, which after removing duplicates and those to do with logistics ended up at around 80, so it took a while to answer them all. I’ll select a couple of good … Read More

Nazita Saye Let’s see a show of hands. How many of you know what I’m talking about? Yes, this was the call to action for Speedy Gonzales, the fastest cartoon mouse (and before the lawyers get involved, Speedy Gonzales and Looney Tunes are trademarks and or trade names of Warner Brothers.

Concurrent CFD Explained (Part IV)

Posted by John Parry

John Parry Last time I promised I’d drill down into more detail about the difference between the CAD-integrated up-front approach to CFD and CAD-embedded Concurrent CFD. CAD-integrated CFD tools are essentially stand-alone tools launched from within the CAD system whereas Concurrent CFD is fully built into the CAD system. So what’s the real difference between the two? CAD-integrated CFD tools use the same approach … Read More

John Parry Back in June I posted ‘Air – Is it Running Out of Gas?’ and put forward the view that for general computing applications air isn’t running out of gas just yet. There are a couple of reasons for that. One is that I suspect the general public has concerns about leaks. Most people have passed cars stuck on the highway with a blown heater hose and seen water on the ground, and I’ve had an automotive water … Read More

EDN Hot 100 Award for FloEFD

Posted by Nazita Saye

Nazita Saye I normally don’t do posts about these kinds of things but I was really excited to hear this. Recently FloEFD was given an EDN Magazine’s Hot 100 Electronic Products for 2009 award. The Hot 100 consists of EDN’s list of “the products and technologies that in 2009 heated up the electronics world and grabbed the attention of our editors and our readers.” Fantastic! I know I’m a proud parent but FloEFD … Read More

John Parry I was on a conference call and WebEx yesterday with the NAFEMS CFD Working Group, of which Mentor Graphics is a member. One of the people on the call had a lot of background noise on his phone, which turned out to be a due to a fan by his desk to keep his computer cool. Computational Fluid Dynamics (CFD) is a memory hungry, CPU intensive activity so I guess he was running a fairly substantial case. … 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
