I found this really useful.
Thanks all.

[QUOTE=Razvan
;145053]Dear Hiras, CFD users,

Initially, I decided not to interfere with your discussion, and that because of several reasons. One of those reasons was the fear of being seen in a "who the hell this guy thinks he is?" way. But now I see that this forum, instead of being helpful at solving one's problems and at the same time giving others the opportunity to learn something, is just allowing some...

Wind Tunnels and CFD

To many observers the rivalry between wind tunnels and CFD is a zero-sum game - as CFD matures it simply replaces wind tunnels. However, this is far from the truth. Often you'll find wind tunnels and CFD used together in a symbiotic process where one technique fills in knowledge gaps left by the other.

The End of Clusters?

Posted March 30, 2009 at 20:58 by gocarts

Are we approaching the end of cluster computing for CFD? Or is it simply the end of the beginning of an era to be further dominated by clusters?

The premise is that a collection of computers (a cluster) can process data in parallel much faster and more cost effectively than a single standalone computer. Until recently clusters were the only viable means to compute large CFD simulations for engineering applications, such as those found in Formula 1.

Now we have available...

Lessons in CFD

Posted March 17, 2009 at 14:15 by gocarts

After an almost endless stream of success stories (at least according to CFD vendors), CFD recently came in for some implied (if not direct) criticism in two widely reported articles. Peering behind the headlines reveals important lessons in benchmarking and the use of CFD.
