Numerical simulation results for the eddy current benchmark problem

This paper presents the numerical simulation results on an eddy current NDE benchmark problem proposed by the World Federation of NDE Centers. The problem involves the calculation of the impedance of a pair of differentially connected coils scanning an infinitely long tube. The excitation source is provided by feeding the coils with an AC current. An edge-based finite element method is used to simulate the problem numerically. Preliminary results obtained using the simulation model are presented.
