An Integral Face Formulation for Thin Non-Conductive Magnetic Regions

This paper deals with the use of the volume integral method to compute the magnetic anomaly created by a non-conductive ferromagnetic thin shell placed in a static inductor field. An original facet integral formulation considering the magnetic induction as unknowns is presented. The use of thin shell element assumption leads to a surface mesh decreasing highly the number of elements so the computation cost. The method is very performing in terms of speed and accuracy.
