ABSTRACT:
A method, an apparatus, and an article for manufacture for modeling an eddy current probe and simulating an eddy current examination of a material is presented. An eddy current probe model of the eddy current probe is produced using a first numerical technique, such as the finite element method. A magnetic vector potential for a surface is obtained from the eddy current probe model, and is transformed. A material model of the material is produced using a second numerical technique, such as the volume integral method or the boundary element method. An examination of the material is simulated using the transformed magnetic vector potential and the material model.
