Hi Andrew,
     did you try Exercise 3 given at the last Fluka advanced course
(in which a dipole is defined both as geometry and as magnetic
field)? This is the link where you can find slides and files:

https://indico.cern.ch/event/489973/timetable/#20160510

If I understand correctly, your problem is very similar.

Hope this helps,
Andrea
