The need to shorten the development time for new engine and vehicles is leading to the increasing use of computational design and simulation methods in the automotive industry. In the last years 3D computational models have been used successfully in vehicle and engine development. It is clear that in this kind of simulation, the input complexity, the output data management and the computational time increase. On the other hand 3D simulations increase the details of the results and their link with the analyzed geometry. During a vehicle design several numerical techniques can be used (finite difference, finite volume, spectral methods, boundary elements, etc.) Often, in a complex simulation, that involves several different physical phenomena such as fluid flow and heat transfer only the use of different simulation techniques allows to obtain good results in a acceptable time. In several industrial applications the use of coupled codes, with different features (1D, 3D or different numerical schemes) could provide an optimal solution for the simulation approach. In this paper an example of a complex simulation of an Under Hood Cooling (UHC) of a vehicle is carried out using two different 3D codes with different numerical approaches with the objective to reduce the simulation time [1].
