Popis: This work presents the determination of the resistance of multilayer grounding systems by a finite elements analysis with an optimization of the soil stratification and an appropriate truncation method for 3D domains. Based on experimental resistivity data, the optimization process of the stratification was carried out by a Genetic Algorithm. The Perfectly Matched Layers technique was used to truncate the 3D open boundary. The results obtained with the association of these two tools developed in this work were validated experimentally.
