The multi-physics theme is a programme of linked activities that improve the simulation capability within the Automotive Design and Engineering process. It is intended that the methods will have application across a wide range of functions, dynamics and attributes of the vehicle. For example; the off-road capability, the effects off real world aerodynamics and the modelling of the noise within the passenger compartment. The ability to apply simulation methods from initial concept through to engineering verification allows robust decision making at all stages of the process. This will shorten product development times, improve flexibility and the ability to respond to market pressures, reduce reliance on physical prototypes and reduce costs and improve competitiveness. The simulation capability will therefore be expanded both in breadth and depth and methods for making simulation tools available throughout the design and engineering process will be explored.
