Abstract :
This paper presents a coupling between integral volume equation method (IVEM) and a fast multipole algorithm (FMM) in order to model ships magnetic anomaly. complex geometries of real vessels associated with dense meshes can be treated in order to compute the magnetic field created by induced magnetization of the hull and coils degaussing systems. Our algorithm has been validated with measurements made on a real submarine mock-up.
