The soil ionization is an important phenomenon to be considered in the analysis of grounding electric systems. In this way, this work has proposed a procedure that allows modeling grounding systems with COMSOL Multiphysics and MATLAB® taking into account the soil ionization effects according to the Dynamic and Energy Balance models. Comparisons between calculated results and those reported in the technical literature showed a satisfactory agreement.
