    I'm trying to predict the performance of an inductor made
    using two different core materials.

    First core material, has extremely low coercivity, less
    than 0.003 Oersteds.  The second, has a coercivity of 0.05
    Oersteds.  The two core materials are placed into the
    materials section using their BH characteristics.

    When running AC analysis, does femm take into account the
    hysteresis losses associated with a more "open" curve core
    material?
