Hardware CAD Server has a feature article on the lastest PC workstations for 3D modeling. The article looks at the immense changes which have taken place in the PC 3D market in the last few years -- driven mostly by 3D games. In addition to looking at professional 3D graphics cards, the article examines the performance of some CAD workstations.

If you are in the market for a new workstation, or would like to know who's leading the field, give the article a read.

Fluent to Offer General Fluid Mechanics and CFD Course
Posted Wed December 12, 2001 @01:37PM
 Print version Email story Tweet story
ANSYS FLUENT Beginning in the second quarter of 2002, Fluent, Inc. will be offering a two-day course as an introduction to fluid mechanics, heat transfer and computational fluid dynamics at two of their US offices. The course is designed to provide a thorough understanding of the underlying physics and numerical techniques of CFD analysis. Attendees are assumed to have a technical background, but not necessarily an engineering degree. The topics are covered in a general fashion with no bias towards any CFD software package.

The first day is a review of fluid mechanics (governing equations, non-dimensionalization, boundary layer flow, internal/external flows, and heat transfer). The second day will focus on CFD techniques including descretization, boundary conditions, meshing considerations, solvers, and post-processing.

For more information, visit the course descriptions online.

Application: CFD Wins Races

Application CFD analysis has played an important role in the performance of winning motor racing teams this year. The dominant Ferrari Formula 1 Motor Racing Team claimed both the Drivers' and Constructors' World Championships. The Ferrari Technical Team utilized extensive CFD simulations with FLUENT to hone the aerodynamics package.

At the Indy 500 race last May, cars manufactured by Italy-based Dallara Engineering finished 1-2-3. Dallara recognized that CFD was essential to their aerodynamic design process and they chose FLUENT to be an integral part of it.

And in the competitive world of NASCAR racing, CFD has found a home in one of the best teams - Joe Gibbs Racing.

Team owner Joe Gibbs remarked, "To win at anything you have to surround yourself with the best. That is why we use FLUENT CFD software to visualize and analyze fluid flows such as air flowing over the vehicle or water flowing through the cylinder head. FLUENT is an integral part of keeping our race teams at their best."

A CFD Haiku

CFD Haiku As a tribute to the "art" of CFD, we are kicking off the Official CFD Review Haiku Poetry Contest. A haiku is a small contemplative poem which valorizes nature, color, season, contrasts and surprises. For our contest, the topic must be related to the field of CFD. The basic haiku format is three lines of 17 syllables arranged in a 5-7-5 pattern.

You are encouraged to send in your CFD haiku for publication here each week. There is no reward other than perhaps personal enlightenment. So, silence the mind, yield to spontaneity and send in your CFD haiku today.

This week's CFD haiku:

Difficult question...
what flow field hidden within?
computer reveals

Application: CFD Used to Study Surface to Air Missles
Posted Mon December 10, 2001 @02:23PM
 Print version Email story Tweet story
Application Scientists at the NAS Division's Applications Branch have used NASA's Cart3D CFD software to analyze the unsteady flight of infrared-guided, man-portable surface-to-air missles (SAMs).

The Cart3D solver's capabilities were extended to simulate the unique flight characteristics of the SAMs which make them difficult to simulate computationally. Scientists used the NASA Advanced Supercomputing facility at Ames Research Center to conduct the steady and unsteady simulations on both a 1024-processor and 512-processor SGI Origin 3000 system. More than 720 simulations were completed on meshes totaling almost 2.4 billion cells.

"Results from preliminary NAS studies presented to the DIA have been met with enthusiastic support," said Mike Aftosmis. The steady and unsteady results have shed new light on the flight characteristics of these missiles.
The Cart3D package is an inviscid Cartesian grid flow solver which provides end-to-end simulation of three-dimensional flows around complex vehicles.
