Use of Scilab to generate compact thermal model based on Zth matrix to speed up thermal simulation

By Patrick Dubus, VALEO

From Computational Fluid Dynamic (CFD) 3D simulation model, results are processed using Scilab scripts to generate compact thermal models. Two models are generated (a mathematical model and a SPICE model using RC cells) and compared to estimate the errors coming from model simplification. Generated model reduces the simulation time by several orders of magnitude and allows to simulated complex scenario coming from real driving road profiles.
