Abstract
Use of a 3D eddy current program to simulate an eddy current probe system is described. Whilst there is great difficulty in accurate representation of fine cracks, the finite-element method works reasonably well for the investigation of thin tubes, and it can model the effects of eccentricities and variations in wall thickness, so long as attention is paid to the meshing
