The present paper describes and clarifies the main difficulties arising in the 3D numerical simulations using finite element method of the remote field eddy current effect in magnetic steam generator tubes. The 2D axisymmetric and full 3D simulations are compared with experimental results from outer discontinuities in Monju fast breeder reactor steam generator tubes. Very good agreements were obtained between measurements and 2D simulations. The influences of several parameters are evaluated by 3D simulations: convergence error of the iterative matrix solutions, pattern of the mesh discretization, the boundary limit and finite element interpolation order. The computational cost of the remote field 3D model in Monju steam generator tubes and the numerical aspects of the 3D simulations are discussed in detail in the paper.
