&CELL: SOLIDS: WIRE

CENTRE

The location of the centre of gravity of the wire.

[No default.]

RADIUS

The radius of the wire.

[No default.]

HALF-LENGTH

Half the overall length of the wire.

[No default.]

DIRECTION

The direction vector of the wire.

The normalisation of the vector is not used. Zero-norm vectors are not acceptable.

[By default, the central axis is aligned with the z-axis.]

VOLTAGE

Voltage of the wire, which is assumed to be conducting.

Specifying this option implies the use of neBEM to solve the field.

FLOATING-CONDUCTOR

The wire will assume a uniform voltage on its surface.

In the process of being implemented.

Specifying this option implies the use of neBEM to solve the field.

material

Specifies which conductor the wire is made of. To differentiate the solids in drawings, one has the option to choose between various representations:

Type Representation Notes
CONDUCTOR CONDUCTORS-1 Equivalent to CONDUCTOR-1
CONDUCTOR-1 CONDUCTORS-1 -
CONDUCTOR-2 CONDUCTORS-2 -
CONDUCTOR-3 CONDUCTORS-3 -

[Default: CONDUCTOR]

label

A one character identification of the solid.

This label serves the same purpose as the wire label for wires, namely the selection of the solid as a place where signals can be measured, around which isochrons are drawn etc.

[By default, no label is assigned.]

discretisation

The approximate linear size of the elements you would like neBEM to use.

Garfield generates for each wire a single primitive: the centre line of the wire. neBEM sub-divides this primitive into "elements", in a process called "discretisation". The sub-divisions of the primitives are called "elements".

Discretisation will perhaps eventually be automated, but for the time being this remains the responsability of the user who has to indicate the length of the desired elements.

The discretisation length has to be given in cm. Also the value AUTOMATIC is allowed, in which case the TARGET-ELEMENT-SIZE will be used that is in effect when the cell section is being left.

[Default: the TARGET-ELEMENT-SIZE that is in effect at the time the solids are read.]
