CFD for Automobile Aerodynamics
Posted Sun January 06, 2002 @11:20PM
Print version Email story Tweet story
News Automotive Design & Production has an article about the use of Exa's CFD code in the automotive industry.

Exa has won the support of a number of automotive manufacturers by modeling not only their test vehicles, but the entire wind tunnel as well. This provided the automotive engineers with a true comparison between the test and analysis results. The CFD results correlated very well.

Now that CFD analysis is viewed as a valuable analysis tool, Exa is promoting analysis early in the design process.

“It’s a real ‘What if?’ tool,” says Stephen Remondi, president, CEO, and co-founder of Exa Corp. “Since you can change your model quickly, cost effectively and have confidence in the simulation, you’re able to try out more aggressive, more creative ideas in the time available.” While it’s presently in the domain of engineers and aerodynamicists, they’re working on a digital interface for designers so that 3D models will be, in effect, “sculpted” as if they were in clay.
Applications include vehicle aerodynamics, underhood thermal management, HVAC, powertrains, air filters, exhaust systems, disc brakes, intake and exhaust manifolds, valves and aeroacoustics.

News Fluent has announced the release of the latest version of their general purpose pre-processor for CFD. GAMBIT 2.0 features an updated geometry kernel which allows for direct access to Pro/ENGINEER's geometry engine and support for ACIS 6.3.

Also new to this release is GAMBIT's ability to automatically refine the mesh in areas of strong curvature and near small gaps. An example of this technology was displayed in the IMR Meshing Maestro award-winning mesh.

A new version of G/Turbo has also been released with GAMBIT 2.0. G/Turbo is an application specific pre-processor integrated into the GAMBIT interface. G/Turbo is a tool which enables the rapid generation of meshes for turbomachinery applications. A unique feature of the pre-processor is the ability to create both structured and unstructured meshes. This allows simple geometries to be created very quickly while also providing a path for analysis of more complex models. G/Turbo is supplied as an add-on to GAMBIT 2.0.

News adapco and TTF have announced the signing of a worldwide partnership agreement which will enable STAR-CD to read native CAD formats.

Trade and Technologies France SA (TTF) develops and markets solutions for CAD model interoperability. adapco will integrate TTF CAD libraries into their software for reading the native formats of the major CAD systems independently of the CAD license.

"We are looking forward to working with TTF towards our goal of bringing our CFD tools more truly into the CAE design engineering environment than has ever been achieved in the fluid flow simulation market", said Steve MacDonald ,chief executive of the CD adapco Group.
There is no word as of yet which CAD formats will be supported, however, TTF claims library support for CATIA, PRO-ENGINEER, UNIGRAPHICS, CADDS, and EUCLID.
