Print version Email story Tweet story
Post Processing ACUITIV™ Software, the leading provider of next-generation Computational Fluid Dynamics (CFD) visualization software, and Ascension Technology Corporation, a leading manufacturer of motion tracking technology, today announced a joint partnership. As part of the agreement, both will participate in joint marketing and sales efforts, as well as complete interoperability testing. With this partnership, users of immersive environments will now benefit from an end-to-end visualization and motion capturing solution set.

As the popularity of immersive environments continues to grow in the automotive, aerospace and defense, energy, and chemical processing industries to better develop, analyze, and collaborate on product designs, ACUITIV Software and Ascension have partnered to offer customers the only combination of products that seamlessly integrates CFD visualization and motion tracking for real-time analysis, interaction, and control. Previously, additional software solutions and complex coding were required to ensure complete interoperability.

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

Print version Email story Tweet story
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.
