Application: Optimizing Santa's Rapid Delivery Vehicle
Posted Mon December 22, 2003 @11:31AM

ANSYS CFX John Stokes,
ANSYS Germany

The CFX Team in Germany was recently approached by a customer faced with the need to deliver his products to an ever-increasing number of clients, in a limited delivery period (one night). At his disposal is a single delivery vehicle, and the propulsion for the delivery vehicle is fixed at 9 RP (Reindeer Power). Therefore, reduced aerodynamic drag could lead to significant increases in vehicle speed, and consequently allow delivery to be made in the required time.

Application: CFD Investigation of High-Pressure Biotechnology

Application by Christoph Hartmann,
Chair of Fluid Mechanics and Process Control,
TU München, Germany

High-pressure food processing, using pressures between 1 and 10 kbar, permits preservation of aroma and vitamins, improvement of textural and sensory properties, and removal of harmful bacteria. The process must be carefully monitored, however, as localized variations in pressure or temperature can significantly influence the removal of bacteria. The process must therefore be uniform, especially in the health-sensitive field of microbial inactivation.

At TU München’s Chair of Fluid Mechanics and Process Control, we are investigating the effect of the fluid dynamics on bacteria during high-pressure food processing. Our research focuses on a 6.3-litre high-pressure chamber that is used to pressurize liquid food contained in five packages, placed on different shelves in the chamber. The chamber is filled with a pressure transferring liquid (in our case water) until the desired pressure level (4 kbar) is reached. The pressure is maintained for about 20 minutes - the time needed to kill the bacteria.

Since experimental methods for investigation at very high pressures, especially for industrial chambers, are not readily available, we have chosen CFD as a means to investigate scale-up and non-uniformity.

Post Processing EnSight 7.6 recently added support for AMD's Opteron and Athlon 64-bit systems running Linux, and support for Apple's Mac OS X platform is under development.

EnSight 7.6 runs as a 64-bit application able to take advantage of increased memory and data pipelines. When installing EnSight, users will find a new machine type, linux_2.4_64, that designates the 64-bit executables for these AMD systems.

Currently, AMD-based Solaris and Windows 64-bit systems are not supported. Contact CEI for these platforms. Running EnSight 7.6 as a 32-bit application under the Windows 64-bit or Linux operating system has not officially been tested nor is it supported.

CEI is currently testing a prototype of its software suite on the Macintosh OS X platform. Included in the suite are EnSight, EnSight Gold, EnLiten and EnVideo. CEI successfully demonstrated these prototype applications at the SuperComputing 2003 conference in Phoenix, Ariz.

New Software: TGS to Support AMD64 & FUJITSU-SIEMENS Celsius V810 Workstation Series
Posted Thu December 18, 2003 @09:18AM
Print version Email story Tweet story
Post Processing TGS, a leading provider of 3D graphics toolkits and advanced visualization solutions, announced its planned support for the AMD Opteron™ and AMD Athlon™ 64 processor architectures with their professional 3D graphics software product lines Open Inventor™ and amira®, for both Linux and Windows operating systems. AMD, Fujitsu-Siemens, and TGS manifest their cooperation by demonstrating selected 64-bit application examples for the launch of the new Celsius™ V810 workstation on December 16th in Dresden, Germany.

TGS Open Inventor is a 3D scene graph API widely used for developing demanding 3D graphics applications. amira, built on top of Open Inventor, is TGS’s flagship visualization application, focusing on interactive analysis, processing, and viewing of three-dimensional scientific data such as 3D imagery (i.e. CT, MRI, PET, 3D ultrasound, 3D microscopy), CAD and polygon models, and vector data (e.g. for flow visualization).
