Re: [femm] How is 5 Tesla possible?

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.
