Density functional theory, however, describes the multicomponent multiphase mixture continuously without density jumps at interfacial surfaces. This is achieved by the introduction into the Helmholz energy, or into the entropy, square component density gradient terms. As a result the hydrodynamics of multiphase mixtures is described in a unified way meaning the governing system of equations is the same at any point in space.

TetGen generates exact Delaunay tetrahedralizations, constrained Delaunay tetrahedralizations, and quality tetrahedral meshes. The latter are quality conforming Delaunay and nicely graded if no input angle is smaller than 60 degree.

The development of TetGen is supported by the pdelib project of Weierstrass Institute for Applied Analysis and Stochastics in the research group of Numerical Mathematics and Scientific Computing.

NAFEMS are now inviting submission of papers for inclusion in the Congress programme. Papers are being accepted from all areas of engineering simulation, under the following broad headings:

• Practical Applications of Simulation
  
• Analysis as an Engineering Tool
  
• Simulation Techniques & Technologies
  
• Successful use of Analysis through Effective Training
• Numerical Methods

With a reputation for technical excellence and innovation, the NAFEMS World Congress is the ideal forum to share experiences, exchange ideas, and gain recognition for innovative work in the simulation field.

BMW ORACLE Racing, is employing the best possible technology in its racing yacht design development. In order to study the dynamics of flow, the design team has selected the CD adapco Group, the leading global provider of computational engineering solutions, to provide CFD (Computational Fluid Dynamics) software.

“For this demanding work we require precision, production capability and some specific functionality only found in CD adapco Group’s software. We work the software hard to achieve an optimal design for our sailors to take into battle for the America’s Cup,” says Ian Burns, BMW ORACLE Racing, Design Coordinator. “By working alongside CD adapco Group we gain a great advantage from having the right tool combined with a great team. We all share a common goal: success.”

The Waterman Group will be applying CFD modelling to areas of its consultancy services including internal ventilation, to design energy efficient natural ventilation schemes, and external flow modelling, which allows the company to accurately predict pedestrian comfort. The company has been involved in the design of a number of major projects, both in the UK and abroad. FLUENT CFD software is currently being used to predict airflow movement to assess occupant comfort for an atrium design study at Saint Katharines Dock (K2) in London, and to model internal ventilation for the White City project in London.

Commenting on the new deal, Vartan Moskofian, Associate designate at The Waterman Group, says: "CFD modelling is an increasingly important aspect of our consultancy services as it allows us to assess a design at the conceptual stage before it is built. However, as with all things, the quality of the tool being used is important to get the right result and in FLUENT we believe we have the best there is."
