In the analysis of time harmonic eddy current testing (ECT) by FEM, in which non-cored exciter/detector coils are moved above the surface of metal object, the use of direct sparse solver has been studied. And it is found practically efficient because the factorized numerical matrix can be reused repeatedly in the calculation. The validity of this method is discussed and a satisfactory result for an ECT model is shown.
