Application: Benetton Formula 1 Using CFD to Design Cars
Posted Sat July 14, 2001 @04:56PM
Print version Email story Tweet story
Application Benetton Formula 1 has begun using CFD for whole-car analysis of their race vehicle. As one of the few teams using CFD for the whole car, Benetton is stepping away from the status quo of using panel method codes for whole-car aerodynamic analysis.

There is a short story about the effort on the CD adapco Group site. They are actually only analyzing half the car, understandable as the grid is still 10 million cells.

Question: Are Local Timestep Methods Bad?
Posted Thu July 12, 2001 @09:00AM
Print version Email story Tweet story
Help Desk I've often wondered about the validity of attaining a steady-state solution with local time-stepping methods (aka CFL number). The problem to me seems that slowing the problem down in one area opposed to another would not yield a global steady-state solution - unless the simulation was run for a very long time even after the residuals have "converged". The residuals are small because the solution is balanced, but the transient processes are not necessarily in balance!

I know these methods are necessary and very useful for cases which have a large (several orders of magnitude) timescale variation, such as jets expanding into quiescent flow, but are the solutions really correct?

SGI Announces Flat Screen Display for Technical Professionals
Posted Thu July 12, 2001 @08:34AM

Hardware SGI is breaking new ground with their line of critically acclaimed flat panel displays. The latest is the F180 Flat Panel Display which boasts an 18.1-inch display with 1280x1024 resolution.

An excerpt from the press release:

The new Silicon Graphics F180 display uses Advanced In-Plane Switching (AIPS) technology in the LCD, which yields higher brightness, increased contrast and wider color gamut than previously available on comparable LCD displays. This leading-edge technology enables more accurate image representation and crisper display for advanced graphics applications such as manufacturing, medical imaging, animation and simulation.
I've seen the older 1600SW Flat Panel and the images are beautiful. The problem I have with digital displays is their inherent "native" resolution and the fact that image quality is poor if you run them at some other resolution. The unit will be available at the end of July and carry a list price of $1,495US.

Purpose of this forum?

CFD Review Philip Jones writes "I read cfd-online and Usenet, then this forum appears. Looking at it, there are 101 registered users and in the current postings there is only one reply and the vast majority of postings are from the owner of the site: and most of these are just the news from other CFD sites. Do people want this forum, if so what should it do and how? The format is very nice but if it is not a forum and just a soapbox for an individual we may as well all go home and leave it to die.

Come on, lets get one article with a few replies and see what the water feels like!"

A very good point - read my reply below.

Sign of the Times at SGI
Posted Mon July 09, 2001 @08:09AM
Print version Email story Tweet story
Hardware In yet another indicator of the troubles at SGI, http://reality.sgi.com, a web server for SGI employees and their families, is being turned off August 15, 2001 after 7 years of operation.

It's too bad because this used to be a place to get games, source code, and irix tips from the great people who worked at SGI.

[Update] SGI announced that they have lost their President and CFO Hal Covert (term of office: two months) and that they will be reviewing their business plans after a disappointing fiscal quarter.
