    I also had a difficulty with using the antiperiodic to
    replicate a structure.  The analyzed result kept giving me
    zero magnetic field at the boundary when I knew there
    should be a strong field coming in one side and exiting the
    other (perhaps, I did not understand the exact meaning of
    the boundary condition).

    However, I solved my problem by placing a magnetic "short"
    around the structure using nonconductive material with a
    relative permeability of 1,000,000   That gave me the
    effect I needed and did not take much overhead in mesh.
