Application Steve Karman and Robert Wilson,
UT SimCenter at Chattanooga,
University of Tennessee at Chattanooga

Modeling of free surface flows for hydrodynamic applications can be accomplished using surface fitting methods for low to medium Froude numbers. But when the Froude number is larger, such as flows associated with steep and overturning waves, the fitting methods encounter difficulties.

The University of Tennessee SimCenter at Chattanooga has implemented a multiphase surface capturing approach to handle these higher Froude number cases, Fr > 0.4. This approach has been applied to several validation cases, including the R/V Athena research vessel shown in this article.

News Sharc Ltd has announced the release of new wrapping software which has been included in the latest version of Harpoon.

Harpoon meshes dirty CAD geometry with ease, however, there are occasions when a wrapper combined with the power of Harpoon would make meshing even easier. In particular, large holes in the CAD can cause problems when creating a mesh. The Harpoon Wrapper alleviates these problems and just like Harpoon, is extremely quick

Application L.L.M. Boermans and J.P. Hemerik,
Delft University of Technology

Research students at the Department of Aerospace Engineering at the Delft University of Technology (DUT) used Gridgen to create high quality grids in their design of the solar powered cars Nuna 2 and Nuna 3 for the World Solar Challenge.

The World Solar Challenge is a biennial solar powered car race from Darwin to Adelaide, Australia. The 3000 kilometer race was won in 2001, 2003, and 2005 by cars designed by DUT.
