    Hello femm group,

    I'm working on magnetic separator and I need to plot
    "grad(H^2)" . Is there a way to do it with lua scripting. I tried a
    finite difference approach using getpointvalue() on a set of
    predefined points but there was too many curve distorsion due to
    derivation error. I'm searching for a way to get more smooth and
    precise curve.
    Any help would be appreciated.

    Mbe.
