Nature of problem:
Given a toroidal magnetic field we seek to describe this field in magnetic field line coordinates. This description is widely used for calculations on plasma motion in magnetic fusion research.
A field line is integrated on a given flux surface. Subsequent Fourier decomposition using Fast Fourier Transform provides the value of the magnetic field in the magnetic coordinates.
This program is applicable to any toroidal confinement system where the magnetic field is known everywhere and whose value is computed from a package supplied by the user.
This depends very much on the quality of the magnetic field representation required. Usually the time is < 120 sec on CRAY-I.
