Lies, Damned Lies, and “CFD Comparison Charts” – Part IV

Posted Aug 26, 2010, by 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

Lies, Damned Lies, and “CFD Comparison Charts” – Part III

Posted Aug 19, 2010, by 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

Lies, Damned Lies, and “CFD Comparison Charts” – Part II

Posted Aug 12, 2010, by 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

Lies, Damned Lies, and “CFD Comparison Charts” – Part I

Posted Aug 5, 2010, by 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
