Abstract

Electromagnetic compatibility (EMC) has become an increasingly important aspect of vehicular design due to the growing integration of electronic and electrical systems, particularly in electric vehicles. This thesis presents an intercomparison of computational electromagnetic methods for vehicle-level EMC analysis. Several numerical techniques, including the finite differencetime-domainmethod, thefiniteelementmethod, andthemethodofmoments, are evaluated using representative vehicular models and excitation scenarios. The numerical methods are implemented using commercial simulation software, namely Ansys, CST, FEKO, and EMCoS. The results reveal significant differences in accuracy, computational cost, and applicability across relevant frequency ranges. In particular, variations in meshing strategies are shown to have a substantial impact on simulation outcomes. Basedonthese findings, practical guidelines for selecting appropriate computational approaches for automotive EMC simulations are proposed, supporting more efficient and reliable EMC-driven vehicle design.
