SGI Altix 3000 Delivers Performance and Productivity for MCAE Applications
Posted Mon March 24, 2003 @02:48PM
Print version Email story Tweet story
Hardware SGI's Altix 3000 system combines the capabilities of Intel® Itanium® 2 processors, the open-source Linux® operating system, and SGI® NUMAlinkTM high memory bandwidth technology. The system has acheived world record performance on industry benchmarks, but it is performance on real-world applications that matters.

In recent tests using CD adapco Group's STAR-CD software for CFD simulation, the SGI Altix 3000 family demonstrated performance and scalability comparable to some of today's best UNIX systems.

"SGI continues to advance their HPC leadership in CFD with the introduction of the new SGI Altix 3000 server. Working together, SGI and CD adapco have achieved several breakthroughs in parallel scalability with STAR-CD simulations," said Peter S. MacDonald, president of adapco and general manager of CD.

Expert Systems Advance Vehicle Aerodynamic Simulation
Posted Wed March 19, 2003 @10:27AM
Print version Email story Tweet story
CD-adapco From the missile shaped design of the modern F1 Grand Prix racing car to the brick-like structure of a heavy truck, aerodynamics plays a crucial role in how well they behave on the road and how efficiently they perform the tasks they are designed for.

For all vehicles, ranging from small passenger vehicles to commercial buses and trucks, reducing air drag is one of the most efficient ways of improving fuel economy. For example, a 5% improvement in drag for a typical diesel engine heavy tuck, which can simply be achieved by improving the design of the wing mirrors, can result in fuel savings of around 500-1000 litres/year for a typical 150,000 km annual highway driving. On the other end of the scale, in motor racing fuel saving might not be the number one priority, but reaching very high speeds certainly is. To propel a typical Class 1 ITC racing car at 300km/h, around 30 kW of additional power is required for a car with drag coefficient of 0.40, compared to one with 0.36. And when you are operating at the limit of your engine, this can make the difference between winning or losing.

One of the first commercial systems to tackle the complex world of external aerodynamics simulation is es-aero. This is a knowledge-based expert system developed by the CD adapco Group and based on the CFD code STAR-CD. The knowledge and expertise embedded in the system comes from many man-years of knowledge and experience gained through the running and analysis of hundreds of external aerodynamic cases, by both the CD adapco Group and its clients and partners.

New Software: FLUENT 6.1 Released
Posted Tue March 18, 2003 @09:20AM
Print version Email story Tweet story
ANSYS FLUENT Fluent Inc. has announced the immediate availability of version 6.1 of its Computational Fluid Dynamics (CFD) software, FLUENT(r). This major release offers several key functionality advantages to FLUENT users, including dynamic mesh for modeling flow conditions in and around moving objects. This easy-to-use capability allows users to simply set up the initial mesh, prescribe the motion, and sit back and watch as FLUENT automatically changes the mesh to follow the motion.

"The new dynamic mesh modeling capability reaffirms our history of innovation," says Fluent's Chief Technology Officer, Dipankar Choudhury. "FLUENT can now easily simulate physical phenomena previously requiring tedious manual preparation. Applications for this new capability include the modeling of automotive in-cylinder flows, store separation and missile launches, moving valves, fuel injector pumps, and mixing equipment. But, really, the applications for this are limitless. Our customers are thinking of new ways to use it all the time," he adds.

Application: Validating CFD with Tomography
Posted Mon March 17, 2003 @02:23PM
Print version Email story Tweet story
Application e3engineering.com has posted an article on the use of CFD to reduce the pressure drop across a fixed catalyst bed reactor by Manchester, UK based ITS.

Initial predictions of the internal flow patterns through the new reactor design were made using a CFD package and gave favourable results. But in many situations CFD models are difficult to validate, and the internal design of this particular catalyst bed, with a non-uniform porosity, made it particularly hard.

In this case, engineers performed validation of the CFD results using electrical resistance tomography (ERT) which uses instantaneous bursts of current to measure the conductivity of the fluid at a plane in the vessel. By injecting a higher conductivity fluid as a tracer and watching it progress through the vessel in time, engineers are able to measure mixing within the vessel.

Combining ERT results from multiple planes of the electrode array produces results which are a reasonable match with the CFD predictions.
