Abstract

An algebraic formulation has been developed for the solution of three-dimensional eddy current problems, according to the cell method philosophy. This formulation is presented in the frequency domain and it is based on the circulation of magnetic vector potential along primal edges and on time-integrated electric scalar potential in primal nodes of conducting region. The formulation has been applied to solve a nondestructive evaluation problem. The flaw has been modeled as a zero-thickness defect and the superposition of effects has been applied to compute the impedance variation with respect to the flawless configuration.
