A numerical simulation tool for multilayer grounding analysis integrated in an open-source CAD interface

In this paper we present TOTBEM: a simulation tool for grounding systems based on the open-source platform SALOME. The package TOTBEM includes all the preprocessing, computing and postprocessing stages necessary to perform a complete earthing analysis. The kernel of TOTBEM is a numerical formulation based on the Boundary Element Method for uniform and stratified soil models proposed by the authors in the last years. Furthermore, in this work we show the main highlights of an efficient technique based on the Aitken δ2-process in order to improve the rate of convergence of the involved series expansions in multilayer soil models.
