The FM design benefits from experience with previous software component efforts, such as the Field Encapsulation Library (FEL). One way that FM differs from FEL is in its open source approach to distribution.

Fields based on computational meshes are defined by associating values with the cells. In computational fluid dynamics (CFD), common examples of fields are the momentum, density, and energy fields surrounding an aircraft.

In analyzing simulation results, scientists are often interested in values derived from the fundamental state variables. For example, they might be interested in velocity or vorticity values derived from the density and momentum fields output by a simulator. Field Model includes classes that provide lazy derived field capability to compute the derived values only as needed, avoiding unused computations and saving on memory requirements.

Working with the NASA Ames Commercial Technology Office, the NAS Data Analysis group has established Field Model as an open source effort. By embracing an open approach, the NAS team hopes to encourage high-performance computing community participation and contributions.

The Field Model project is based at SourceForge.

To solve the problem, NASA has helped to create the concept of a computational grid. A computational grid is a network of geographically and often organizationally distributed resources including computers, instruments, and data. A user has single-sign-on access to all the resources on a grid.

Currently the three most substantial grids, in terms of compute cycles already provided, persistence, and scope of resources, are:

• The NSF PACI/NCSA Alliance Grid
• The NSF PACI/SDSC NPACI Grid
• The NASA Information Power Grid

The NASA Information Power Grid (IPG), which connects several NASA centers, makes available supercomputers, high-end scientific instruments, and terabyte datasets.

As grids grow, grid communities will be looking for scientists and computer engineers to help build grids or to use grids for research. The NASA Advanced Supercomputing (NAS) Division at Ames Research Center is a focal point for the joint university and government creation of NASA’s IPG. To discuss possible opportunities for internships or collaborative research, contact Arsi Vaziri, IPG Deputy Project Manager, at avaziri@mail.arc.nasa.gov.

Industry technology experts will host an interactive presentation followed by a 30-minute Q & A session. Utilizing the HP Chipset zx1, the new Itanium 2-based systems deliver break-through performance beyond the limitations of RISC, the broadest O/S coverage and at the lowest price. Content will include product details, performance, availability, roadmaps, and customer successes.

Objectives of the meeting

• To enable you to meet with employees of the CD adapco Group and fellow CFD users
• To allow us to tell you about new features and developments of STAR-CD and its associated expert system tools
• To provide an opportunity for you to listen to presentations given by our users across all industry sectors
• To attend an exhibition by our hardware and software partners
• To enjoy a boat trip on the Thames, on the Monday evening

How to present

If you would like to make a presentation, could you please send your proposed title and an abstract of 150-200 words to info@cd.co.uk Typical papers would cover one of the following topics:

1. How CFD with STAR-CD has enabled you to conduct fundamental design, which would otherwise be extremely difficult or impossible.
2. How CFD has helped you to reduce time to market and minimise design costs.
3. How STAR-CD was utilised to improve the existing design of your products.
