Print version Email story Tweet story
Hardware techman writes "AMD has released and Opteron Model 146 for 1P workstations and Opteron Model 846 for 4- to 8-way-capable servers , both at 2GHz.

The AMD Opteron processor is based on AMD’s eighth-generation processor core, which marked the introduction of AMD64, the industry’s first 64-bit, x86 technology implementation. This technology preserves companies’ investments in 32-bit applications, while allowing a seamless transition to 64-bit computing as those companies require. The AMD Opteron processor is designed to deliver high-performance server and workstation solutions for today’s most demanding enterprise applications. The processor is scalable, reliable and compatible, which can result in lower total cost of ownership. Key AMD Opteron processor innovations include an integrated memory controller, which reduces memory bottlenecks, and HyperTransport technology, which increases overall performance by removing or reducing I/O bottlenecks, increasing bandwidth and reducing latency.

Application: Assessing Wind Power Potential of a Site with CFD
Posted Tue September 09, 2003 @08:29AM

Application By Christiane Montavon,

The power and energy output of a wind turbine is a cubic function of the wind speed. Doubling the wind speed can mean a substantial increase in the energy output, thereby improving the economic viability of an installation. It is vital to assess the wind power potential of a site with as much accuracy as possible, taking into account seasonal as well as year to year variations in the local wind climate.

The standard way to assess the potential of a site is to measure the on-site wind conditions carefully and consistently for at least a year. Since wind conditions can vary significantly from year to year, measurements are usually correlated with measurements taken at a nearby site, for which a longer-term record is available. The measurements at the site of interest are then 'corrected' for the long-term trend.

At the time of assessing the wind energy potential of the site of Mt-Crosin East, Jakob Vollenweider, of the Swiss utility company JUVENT, considered an alternative option. In addition to a short-term measurement campaign, he commissioned a CFD analysis of the wind conditions on the site, which, together with a long-term data set at the meteorological station of Chasseral a few kilometers away, allowed construction of wind potential maps in the area of Mt-Crosin.

Civil Protest Against CFD?
Posted Mon September 08, 2003 @08:44AM
Print version Email story Tweet story
News Last week a group of people staged a protest outside Fluent's Sheffield, UK offices. Citing Fluent's "use of software for airflow modelling of missiles", the group was more likely trying to gain pubilicity for themselves by staging an early protest against this week's DSEi defense conference in London, of which Fluent is an exhibitor.

According to this report, four people barricaded a revolving door, two others locked themselves to the door using bicycle locks, and others hung banners including "Fluent Deal in Death" on the main entrance.

Police failed to stop the action because "work was not stopped" (a backdoor remained open), however, they are fortunate that an emergency did not occur in the building with the main entrance blocked.

Civil action has its place, but it is clear that this group is misguided -- another website reported the action as "Sheffield Arms Traders Targeted".

Business: Blue Ridge Numerics Named to Deloiite & Touche Fast 50

News Blue Ridge Numerics Inc. announces that it has been named to Deloitte & Touche’s Technology Fast 50 Program for Virginia, a ranking of the 50 fastest growing technology companies in the area by Deloitte & Touche. Rankings are based on the percentage of growth in fiscal year revenues over five years, from 1998-2002.

Blue Ridge Numerics has grown its operating revenues over the past five years by 415% while other computer-aided engineering software companies have struggled to sustain even modest growth. The company’s success is attributed directly to the increasing popularity of CFdesign, its flagship software product.

CFdesign is virtual prototyping software that saves companies money and time by reducing the amount of wind tunnel and flow bench testing necessary to validate new designs.

CFD and FEA Meshing Overview
Posted Thu September 04, 2003 @08:53AM
Print version Email story Tweet story
Grid Generation Mechanical Engineering magazine has posted an overview of grid generation for FEA and CFD analysis. "making a mesh of things" covers developments in meshing in the last few years and explains the trade-offs associated with "simple meshing".
Pre-processing mesh technologies can now automatically generate the mesh necessary for analysis. Like most things, this is both good and bad. It means that expert analysts need not be involved in simple analysis, but it also means the software design engineers can run analyses without fully understanding FEA methodology, which could affect design.

Print version Email story Tweet story
News CFX recently joined the ANSYS family to incorporate state-of-the-art CFD technology into the ever-growing ANSYS suite of simulation solutions. As a long-standing strategy, ANSYS strives to provide a robust multiphysics capability that enables companies to simulate the performance of complete products in their intended environment.

With CFX, increasingly powerful simulations are available throughout all stages of the product development process.

A wide variety of industries have already benefited from this technology, you should too!

To learn more about how ANSYS, ICEM CFD and CFX software are evolving together, join us for a live web seminar on September 3 or September 17 at 1 pm EDT.

In addition, join us September 25 or October 23 at 2 pm EDT for a live web demonstration of CFX-5 in action. For those unfamiliar with CFX-5, this demonstration illlustrates why CFX-5 is the best-in-class CFD software available today. Features of CFX-5 to be demonstrated include grid adaption, parallelization set-up and CFX Expression Language.

Visit the seminar website to register.

Sorry, these events are only available in North America.
