Method of boundary integral equations in magnetostatic damping of thin shells

Object and purpose of research. Calculation of the surface current density needed to compensate magnetic signature of thin ferromagnetic shell. Materials and methods. Numerical methods for boundary integral equations. Main results. Numerical solutions are considered for the densities of the inner and outer current layers which compensate external magnetostatic signature of closed ferromagnetic shells of arbitrary shape. The effect of mesh size and surface magnetism approximation upon the compensation error was investigated on test models. Conclusion. The results of the research can be used to optimize the location of degaussing coils aboard offshore objects (the geometry is taken into account).
