Here is a direct link to the rebuttal article: "Lies, Damned Lies, and "CFD Comparison Charts" - Part I" You can also see the original "comparative charts" here as reference.
In this article, Dr. J aptly points out the one-sided take by CF Design. Though he mainly talks about improper comparison of Mentor Graphics' FloEFD, there are several inaccuracies on this comparative chart when it comes to ANSYS CFD products (FLUENT, CFX) as well. Any current FLUENT and CFX user can testify to these inaccuracies! Dr. J, the count on "misleading statements" in the DE article are well beyond 27 if we include the ANSYS CFD products. I still don't believe this article ever got published! It begs more research and accurate information.
Having been in the simulation industry (FEA, CFD) for close to a decade, this false comparative chart regarding CFD products is really appalling, especially coming from a magazine such as DE. Negative marketing campaigns are not a good idea. If you do them, please know the facts about competition first! And then do not do it as a "guide" to helping engineers decide on what CFD code to chose!
Update: Folks from Blue Ridge Numerics have responded on LinkedIN forums on this and seems like they are working on it. Good to know:) You can follow their comments here: www.linkedin.com/groups?home=&gid=66032
I look forward to your feedback.
