VITESS Module Quadrangular Field


The module quadr_field simulates a magnetic field of constant field intensity in the shape of a a quadrangular or triangular prism. Outside this range, a zero magnetic field is assumed. If the edges ABCD and EFGH (cf. Figure) lie on planes each, which are not parallel, it can be treated as well.
The 3 components of the magnetic field and the origin of the new co-ordinate system have to be given (cf. figure).

Figure: quadrangular field

The positions of the 8 points marking the vertices of the prism have to be given in a file that looks like that:
#   x     y     z
#---------------------------------
  20.0 -30.0   5.0   # A
  60.0 -35.0   5.0   # B
  50.0  40.0   5.0   # C
  30.0  30.0   5.0   # D
  20.0 -30.0  -5.0   # E
  60.0 -35.0  -5.0   # F
  50.0  40.0  -5.0   # G
  30.0  30.0  -5.0   # H
For a triangular prism, points D and H have to be set identical to C and G (see figure). Everything behind a '#' symbol is treated as a comment.
