Abstract: Various computational modeling techniques have been proposed for the transient analysis of pulsed eddy current PEC modality. Two widely used modeling approaches are investigated. The first is based upon harmonic analysis using finite element method FEM, and the second depends on finite-different time-domain FDTD technique. Diffusion fields based on quasi- static formulation are modeled with the FEM, while full-wave analysis is offered by the FDTD. Reduction of the number of time iterations in FDTD is achieved by two translation types: frequency- conductivity and wave speed. Comparison is presented based on results obtained using both approaches, including the encountered limitations, required resources and performance. © 2009 American Institute of Physics.
