Hockey Puck Aerodynamics
This blog has been in the works for about a year. I think it was worth the wait. Let me explain, as a number of things were at play here. First, I had just attended a Siemens NX CAD system training in advance of our release of FloEFD for NX last year. So I was looking for an application I could cut my teeth on for my first FloEFD for NX analysis. Something with CAD … Read More

Smoke, Smoke, Everywhere?
This has the possibility to be my most unpopular blog ever, which I’m ok with. The topic of this blog is smoking, specifically the second hand kind. Let me start by saying I am not a smoker. I don’t care for the smell, and am happy that it is not allowed in most building, Vegas casino’s being the main exception. My mom was for a long time though, and in general it seems … Read More

Welcome to Part IV of a multi-part series, where in this installment Travis continues the “virtual” look at his crawlspace.
In the previous installment of “this old CFD house”, we started to peel back the veil on my crawlspace and its moisture issue. I analyzed the problem as it is, and we made some enlightening findings. First, really the only way air is getting into the crawlspace is … Read More

Welcome to Part III of a multi-part series, where in this installment Travis takes a “virtual” look at his crawlspace.
For this next installment of “this old CFD house”, and really the entire reason I started this blog series, I’d like to take a look in my crawlspace. Now, from what I understand, Feng Shui says running water is good for wealth. Well the opposite is true when you have … Read More

Welcome to Part II of a multi-part series where, in this installment, Travis takes a look at a typical chimney.
For this next installment of “this old CFD house”, I’d like to investigate another gremlin that was discovered during the inspection period of the house we are purchasing. This one related to the chimney. The current damper is rusted and hard to operate. According to the chimney expert we … Read More

I’d like to introduce my first guest blogger, Travis Mikjaniec. Travis is a colleague of mine who is entering the world of home ownership. Travis has questioned some of the recommendations from the various home inspectors. In a multi-part series Travis will debunk or otherwise quantify the value of the recommendations.
Starting the process of buying a house is a daunting task. Beyond all the … Read More

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

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
