This paper describes the use of integrated multidisciplinary analysis and optimization of a race car
model on a predefined circuit. The objective is the definition of the most efficient geometric
configuration that can guarantee the lowest lap time. In order to carry out this study it has been
necessary to interface the design optimization software modeFRONTIER with the following softwares:
CATIA v5, a three dimensional CAD software, used for the definition of the parametric geometry;
A.D.A.M.S./ Motorsport, a multi-body dynamic simulation software; IcemCFD, a mesh generator, for
the automatic generation of the CFD grid; CFX, a Navier-Stokes code, for the fluid-dynamic forces
prediction. The process integration gives the possibility to compute, for each geometrical configuration,
a set of aerodynamic coefficients that are then used in the multiboby simulation for the computation of
the lap time. Finally an automatic optimization procedure is started and the lap-time minimized. The
whole process is executed on a Linux cluster running CFD simulations in parallel.
