Abstract :
A procedure is proposed to efficiently model thin wires in lossy medium by finite element analysis. It is based on the determination of a suitable grid size in the vicinity of the wire, which strongly depends on the wire radius to yield accurate results. The approach is well adapted to the analysis of grounding systems.
