Call: GET_WIRE_DATA


wire

Should contain the number of the wire when the procedure is called.

This argument is mandatory and is not modified.

[No default.]


x

Contains, on return, the x- or rho-location of the wire in cm for x, and log(cm) for rho.

If the cell has been entered in polar coordinates, then the wire location is returned in internal coordinates. These can be converted to Cartesian or polar coordinates with the INTERNAL_TO_CARTESIAN and INTERNAL_TO_POLAR procedures.

This argument is optional. The argument should be a global variable, not a constant nor an expression. The global may have been declared prior to the call, but doesn't have to. The value an existing variable had before the call will be lost.


y

Contains, on return, the y- or phi-location of the wire in cm for y, and in radians for phi.

If the cell has been entered in polar coordinates, then the wire location is returned in internal coordinates. These can be converted to Cartesian or polar coordinates with the INTERNAL_TO_CARTESIAN and INTERNAL_TO_POLAR procedures.

This argument is optional. The argument should be a global variable, not a constant nor an expression. The global may have been declared prior to the call, but doesn't have to. The value an existing variable had before the call will be lost.


V

Contains, on return, the potential at the wire surface as entered with the ROWS statement in the &CELL section. The potential is returned in Volts.

The CHECK instruction can display the potential that is computed for the neighbourhood of the wire.

This argument is optional. The argument should be a global variable, not a constant nor an expression. The global may have been declared prior to the call, but doesn't have to. The value an existing variable had before the call will be lost.


q

Contains, on return, the charge that has been computed for the wire. The unit of charge in Garfield is 1/Volt.

This argument is optional. The argument should be a global variable, not a constant nor an expression. The global may have been declared prior to the call, but doesn't have to. The value an existing variable had before the call will be lost.


label

Contains, on return, a character string with the label of the wire.

This argument is optional. The argument should be a global variable, not a constant nor an expression. The global may have been declared prior to the call, but doesn't have to. The value an existing variable had before the call will be lost.


length

Contains, on return, the length of the wire, in cm.

This argument is optional. The argument should be a global variable, not a constant nor an expression. The global may have been declared prior to the call, but doesn't have to. The value an existing variable had before the call will be lost.


weight

Contains, on return, the weight with which the wire has been pulled during assembly, in grams.

This argument is optional. The argument should be a global variable, not a constant nor an expression. The global may have been declared prior to the call, but doesn't have to. The value an existing variable had before the call will be lost.


density

Contains, on return, the density of the material of which the wire is made, in g/cm3.

This argument is optional. The argument should be a global variable, not a constant nor an expression. The global may have been declared prior to the call, but doesn't have to. The value an existing variable had before the call will be lost.
