CALL: WEIGHTING_FIELD_3


coordinates

  WEIGHTING_FIELD_3 uses the internal coordinate system. If you
  describe your cell in Cartesian coordinates, then the internal
  frame is simply the Cartesian coordinate system. If you use
  polar coordinates however, then you should supply the following
  parameters:

  for x: log(r)
  for y: phi, in radians
  for z: z

field

  The field is returned in internal coordinates. The internal
  coordinates system is Cartesian when the cell is described in
  Cartesian coordinates, but when you describe the cell in polar
  coordinates, you've to apply the following mapping:

  Er   = Ex/r
  Ephi = Ey/r
  Ez   = Ez

wire

  Here you have to enter the sense wire group number of the
  electrodes on which you wish to measure the current. This
  number can be obtained by typing SELECT without arguments.

  This argument is compulsory.

copy

  In periodic cells, the x and y copies of the basic cell
  register different currents than the basic cell.

  By default, you get the field from the basic copy of the
  cell. If you wish to see the field from another copy,
  then you have to specify the x and/or y copy number as
  appropriate.
