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

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

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

I recently read an excellent white paper from Cyon Research titled “Classes of MCAE Software: Clarifying the Market”.   It spoke about the requirement in the industry and the characteristics for CFD software packages that were targeted for use by the CFD specialist.  It also emphasized that the emerging need was for CFD software that could be used by the design engineer who was not a CFD specialist. … Read More

We are all familiar with Computational Fluid Dynamics (CFD).  Some of YOU are experts in this science/art and use it on a daily basis to solve some of your most complex fluid flow and heat transfer problems.  Some of US can hardly spell CFD and as engineers design their products they depend heavily on the CFD specialists to perform the simulations that determine if what they are designing will work … Read More
