June 10, 2002 -- Lebanon, NH and Tokyo, Japan. Earlier this year, the Japan Society of Automotive Engineers JSAE invited the major CFD software vendors who serve Japan's automotive industry to take part in a benchmarking exercise which tested CFD predictions on six classical automotive problems. Fluent Asia Pacific, Tokyo, Japan, using the worldwide company's flagship product, FLUENT, was one of the few companies to successfully complete all of the challenge problems with a high score. The test cases included:

• External aerodynamics
• HVAC climate control in an automobile cabin
• Static port modeling for internal combustion engine analysis
• HVAC defrosting of an automobile windscreen
• Automatic meshing capabilities
• Visualization capabilities

Although Fluent has numerous turbulence models and wall functions, the rules of the competition specified that participants use the default turbulence model without modifying any of the turbulence model constants. Fluent employed the realizable k-epsilon model throughout. Participants were, however, allowed some flexibility over the mesh design. A tetra mesh with a hybrid prism near the surface proved to be most popular. In addition to checking the accuracy of the solutions against experimental data, the calculation speed and memory requirements were also taken into consideration. In all these important areas, FLUENT performed well. A full description of the results is available from the Japanese Society of Automotive Engineers www.jsae.or.jp.
