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.

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.

The 12th International Meshing Roundtable
will be held in Santa Fe, New Mexico, USA, on September 14-17, 2003.
In 1992, Sandia National Laboratories started the Meshing Roundtable as a small meeting of like-minded companies and organizations striving to establish a common focus for research and development in the field of mesh and grid generation. Sandia National Laboratories continues to organize the International Meshing Roundtable, which has become recognized as an international focal point annually attended by researchers and developers from dozens of countries around the world. The relaxed atmosphere at each Roundtable provides an open and technically rich environment in which to share new ideas and technical advances.
The International Meshing Roundtable continues to focus on bringing together researchers and developers from academia, national labs and industry in a stimulating, open environment to share technical information related to mesh generation and general pre-processing techniques. In 2003, Roundtable attendees will enjoy Santa Fe's unique Southwest architecture, picturesque streets, Loretto Chapel and miraculous staircase, distinctive regional foods, fine museums and art galleries. Santa Fe is filled with 400 years of history and culture. The conference hotel, Inn at Loretto, is within walking distance to the plaza, Palace of Governors and other attractions.
