SGI Origin 300 a Gem for Low-Cost HPC
Posted Thu December 20, 2001 @11:30AM
Print version Email story Tweet story
Hardware Many mechanical computer-aided engineering (MCAE) applications benefit from high-performance computing (HPC) technology. CFD in particular benefits from the large memory bandwidth and fast processors of HPC machines. CFD also benefits extremely well from parallel environments, efficiently scaling to hundreds of processors.

A system architecture that can achieve high parallel efficiency becomes important for large CFD simulations. The same multiprocessor architecture found in the largest shared memory parallel (SMP) system currently available, the SGI Origin 3800, is available in the more affordable SGI Origin 300 system.

The HPC technology offered with the new midrange SGI Origin 300 server is well-suited to the demands of each MCAE application segment. In particular, the choice offered with SGI Origin 300 as a moderately configured SSI for departmental deployment, or as a large cluster for scalable DMP applications, provides substantial performance benefits to MCAE applications for a range of modeling requirements.
Using the SGI Origin 300, CFD simulations can be performed at levels nearly equivalent to the industry-leading SGI Origin 3000 series up to 32 processors, but at roughly half the cost.

AIAA CFD Drag Prediction Workshop Results
Posted Wed December 19, 2001 @12:27PM

News The AIAA CFD Drag Prediction Workshop was held June 9-10, 2001 in Anaheim, CA. The workshop was held to assess the state-of-the-art in computational methods for aircraft force and moment prediction with emphasis placed on the prediction of drag polar and drag rise.

The test configuration was a DLR-F4 model which had been tested in three European transonic facilities. Participants were provided with multiblock structured, overset, and unstructured grids on which to perform baseline cruise-point calculations.

Twenty participants provided solutions and 51 individuals attended the workshop from the U.S., Canada, Europe, and Brazil. At the cruise point, the standard deviation of CFD solutions was 20 drag counts (0.0020), whereas the standard deviation in the wind tunnel data was approximately 5 drag counts. A similar workshop held in the 1990s used the same geometry and resulted in a standard deviation of approximately 50 drag counts.
The results and remarks are available online.

The Role of CFD in Virtual Engineering
Posted Tue December 18, 2001 @07:00PM
Print version Email story Tweet story
News P.S. MacDonald, Director and General Manager of CD adapco Group, has written an editorial on the value of virtual engineering and how he sees CFD being integrated into the design cycle.
Virtual engineering is not a route that allows half measures. To avoid building multiple prototypes, all aspects of product development must be captured and closely integrated. For example, vehicle design engineers may need to simulate a crash, and at the same time optimise underhood thermal management.

The article goes on to describe the steps being taken at CD adapco Group to help establish the virtual engineering process.

CFD Haiku This week's CFD haiku comes from willjefc:
Computer our friend?
Try a small mesh size problem
Testing not so bad.
Send in your CFD haiku for publication here each week. There is no reward other than perhaps personal enlightenment. So, silence the mind, yield to spontaneity and send in your CFD haiku today.
