Robert,

Harmonic problems (i.e. where frequency is not zero) are solved linearly by
FEMM, it doesn't include saturation so any value of B can be achieved. Dave
has recently produced a development version which can deal with non-linear
problems, which is (I think) currently version 3.3alpha2.

Try that.
