    As far as codes with some user interface capabilities, check out:

    gmsh/GetDP at http://www.montefiore.ulg.ac.be/services/elap/elm_en.html

    Radia at
    http://www.esrf.fr/machine/support/ids/Public/Codes/Radia/Radia.html

    You might also take a look at EMAP: http://www.emclab.umr.edu/emap.html
    This code does 3-D analysis, but it runs from the command line, and doesn't
    have any pre- or post-processing capabilities. You also have to compile it
    yourself, but there are good, free C compilers out there (i.e. djgpp) that
    you could use to do the job, if you don't already have one.

    I haven't really though about inverse methods, so I don't have any articles
    that I can recommend. There was a thread related to this in
    sci.physics.electromag about a month ago (search DejaNews for the original
    post and follow-ups to "Lagrangian FROM evolution equations?"), but I don't
    think any good reference were cited.

    Getting slightly off-topic here, NASA-Marshall has put out a press release
    about a machine that I designed. This machine is perhaps the first machine
    designed with the aid of femm, so I suppose that this is sort of like
    showing off baby pictures. If you are interested, check out:
    http://www1.msfc.nasa.gov/newsroom/news/releases/2000/00-023.html
    It's the "Second magnetic levitation track installed at NASA Marshall" part
    of the press release, and there are links to pictures of the machine and a
    quicktime movie of the machine in action.

    Dave.
