Application: Heatsink Designers Turn to Computational Fluid Dynamics

Print version Email story Tweet story
Application The accelerated release of faster desktop computers being sold at lower prices into the market place has forced thermal engineers to develop and optimize thermal solutions that not only perform better thermally and acoustically, but deliver more value with less weight than previous generations. The continuing reduction in form factor has also increased the challenge placed on today's thermal management designs.

To meet these challenges, Tyco Electronics utilized CFD analysis to optimize both cost and thermal performance of next generation radial folded fin (RFF) heat sinks. This optimized thermal solution approach produced a scalable design capable of meeting the rapidly evolving requirements of the computer market.

News Don writes "We are planning to put a flow solver on the market and are doing a customer survey. We are planning to customize the software for various applications and want to see what is of most interest.

A web page giving access to a free hybrid grid generator controlled by a GUI plus related source code and a CFD screen saver will be made available to anyone who fills out the survey with care and sends it to before January 18."

Help Desk ddunava writes "Am using CFX. Have 3 Gb RAM. Operating system is Windows XP. Have booted in safe mode with networking enabled. Am only able to obtain 1275 Mb of memory. Solver is requesting about 1.4 Gb of memory and fails. My understanding from a couple different sources is available memory should be somewhere between 1400 and 1900 Mb in safe mode. Need assistance ASAP, thanks."

Linux: A Revolution in Scientific and Technical Computing

News SYS-Con India is running an article on the growth of Linux clusters in scientific and technical computing, the technical hurdles involved, and the potential cost savings.
Many researchers and engineers have made Linux their operating environment of choice due to its wide familiarity, broad support, and ease of use for both users and administrators. Today Linux clusters are the fastest-growing type of HPC system. Clusters represented a third of the technical server market in 2004 and half the market by the first quarter of 2005. And, between 2002 and 2004, revenue from Linux-based systems more than quadrupled. In addition, key applications in many fields - including most independent software vendor (ISV) applications such as computational fluid dynamics codes used for computer-assisted engineering (CAE) - are now certified for Linux and many were even designed to run specifically on Linux.

Application by Dr. Peter S. Weitzman
Concepts NREC

Automated optimization in the turbomachinery design process has long been an objective of many designers and a topic of study by several companies. Concepts NREC first responded to the need for such a practical system in 1997 when the company received funding from NASA to integrate iSIGHT software from Engineous Software into it's own Agile Engineering Design System.

This early work focused on using optimization algorithms to manipulate the geometries of centrifugal pumps, fans, and compressors, with the analysis of each candidate design being conducted using a rapid streamline curvature (SLC) solver. [1]

New Software: ALGOR Launches FEMPRO Pre-Processing Software
Posted Thu January 05, 2006 @06:25PM
Print version Email story Tweet story
News ALGOR, Inc., a leading provider of design, analysis and simulation software, announced the immediate availability of FEMPRO, which has been designed to compete with Femap in the arena of pre- and post-processing for NASTRAN-compatible and other finite element analysis (FEA) software.

"FEMPRO is a modern, easy-to-use and complete system with full finite element modeling, results evaluation and presentation capabilities. Using FEMPRO, users build FEA models which can be processed by a variety of solvers for the purpose of performing mechanical simulation, which is often called virtual prototyping," said Bob Williams, ALGOR Product Manager.
