&OPTIMISE: ADD

length

The length of the periodicity, in cm for x and y, in degrees for \φ. Periodicities in \φ must divide 360\°, they are rounded if that is not the case.

Periodicities in r are not permitted.

The position of the plane, in cm for x, y and r, in degrees for \φ. The r coordinate of a circular plane must be\ >\ 0.

[This is a mandatory parameter; no default is provided.]

The potential of the wire or the plane in Volt

[Default: 0\ V].

A single character by which you can identify the wire or the plane in SELECT statements.

The label 'S' has a special meaning in that electrodes with this label are by default selected.

[Planes are by default not given a label, a label is mandatory for wires.]

The location of the new wire.

This is a set of two numbers (x,y) or (r,\φ) depending on coordinate_system used when the cell was entered.

The units of x, y and r is cm, \φ is in degrees.

[No default, these are mandatory parameters.]

The diameter of the new wire, expressed in cm.

[Default: 0.01\ cm.]

The weight used to stretch the new wire, expressed in grams.

Used by the FORCES command to estimate the wire displacement under gravitational and electrostatic forces.

[Default: 50\ grams.]

The length of the new wire, expressed in cm.

Used by the FORCES command to estimate the wire displacement under gravitational and electrostatic forces.

[Default: 100\ cm.]

The density of the material of which the new wire is made, expressed in g/cm\³.

Used by the FORCES command to estimate the wire displacement under gravitational and electrostatic forces. Not relevant if the wires are vertical.

For copper-beryllium wires, one can also enter CU-BE and for gold plated tungsten one can type TUNGSTEN or W.

[Default: 19.3\ g/cm\³, i.e. 20\ \μm gold-plated tungsten wire.]
