    Dave..

    I try to calculate forces in a PM-iron structure (please see attached
    .fem file). I'm using the boundary condition in order to modify the
    position of the stator (central part of the structure). The problem is,
    even thought I the stator is smooth (no slot) I'm getting different
    force values for different position, which is unexpected. If I have
    smooth surface, I don't have cogging force. However, the magnetic energy
    is constant for any position. What could be the problem?

    thanks

    Juan
