British software helps design Japanese cars

Japanese cars will be designed using software developed in Britain, after a manufacturer decided it is the most advanced software on the market.

To help it design future models, Daihatsu has bought the latest version of AEA Technology’s CFX-5 for its ability to model flows of both gases and liquids around and inside vehicles. The software can be used to optimise aerodynamic design, to predict the performance of ventilation and heating systems, or to simulate the flow of liquids in the engine and braking systems.

It offers a new technique (automatic hybrid meshing), which means designs created with CAD can be easily translated into a CFD computer model, and supports a mesh of both pyramid (tetrahedra) and prism elements, which enables it to build very accurate models. Mesh generation time is also shorter becasue it uses data directly imported from CAD.
