Magnetic field component.

Identification

• Author: Erik B Knudsen, Peter Christiansen and Peter Willendrup
• Origin: RISOE
• Date: July 2011

Description

Region with a tabled magnetic field read from file.
The magnetic field is read from a text file where it is
specified as a point cloud with N rows of 6 columns:
x y z Bx By Bz
the B field map is resampled with Stepx*Stepy*Stepz points.
Use Stepx=Stepy=Stepz=0 to skip resampling and use the table as is.
The regions itself may be either a 3D rectangular block, a cylinder with axis along y,
or spherical. Interpolation is done between data-points.

Input parameters

Parameters in boldface are required; the others are optional.
