[Getdp] Calculation the mechnical force between magnets.

[Bernhard Kubicek]

Dear Sebastian, 
I just played around a bit with your files, and maybe I have a method
that somehow can calculate the force.
You create different meshes, where the magnets are varied in position.
As an output for each mesh, you calculate the total field energy.
the force should then be the variation of the field energy divided by
the dislocation distance.
but I have not verified things, only thing is I wrote an script that
does the variation.
after the script (that should work with linux after setting the paths
correctly, or with cywin in windows) you can do the manual calculations
to get the force.
I _think_ that you just need to add the field energies of all domains.
but what confuses me is that the magnets have negative energy?? I quite
in a hurry now, and cannot investigate much further right now.
nice greetings,
bernhard
