This communication presents the first development aiming at efficiently simulating configurations of eddy current thermography for nondestructive evaluation. The numerical method proposed here is based on the Finite Integration Technique for both electromagnetic and thermal problems. Simulation results obtained using two different materials, steel and aluminum, are compared and discussed with respect to the presence of a flaw affecting the piece under test.
