Fluent and ABAQUS to Deliver Coupled Fluid-Structure Analysis Capability
Posted Tue December 23, 2003 @05:05PM
Print version Email story Tweet story
ANSYS FLUENT Fluent Inc., the leading provider of computational fluid dynamics (CFD) simulation software and services, and ABAQUS, Inc., the leading supplier of software and services for advanced finite element structural analysis (FEA), announced today the formation of a strategic technology initiative to develop and support coupled fluid-structure simulation capability. The collaboration will leverage the best-in-class tools of each company to deliver co-simulation capability for fluid-structure interaction (FSI), enabling manufacturers to address complex design problems in the automotive, aerospace, biomedical, and process industries among others.

Currently, engineering analysis of stress and thermal effects in structures is typically performed in isolation from the analysis of fluid flow phenomena, despite the impact of flow-induced forces and heat transfer on a structure and the impact of a structure on the fluid. The Fluent-ABAQUS initiative will provide engineers with easy-to-use tools that will take into account these important coupling effects including sophisticated simulation of nonlinear structural responses.

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.

Print version Email story Tweet story
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.
