Control Cards

Control cards are used to specify requests and solver settings and are placed after the EG card in the .pre file.

Table 1. Control Cards.
Card Description
A0 Defines a linear polarised plane wave incident on the structure.
A1 Defines an excitation by means of a voltage gap on a segment (impressed electric field strength along a segment).
A2 Defines an excitation by means of a voltage gap at a node (between two segments).
A3 Defines an excitation by means of a magnetic ring current (TEM-frill) on a segment to model a coaxial feed.
A5 Defines an excitation by means of an electric Hertzian dipole. The position and orientation in space are arbitrary.
A6 Defines an excitation by means of an magnetic Hertzian dipole. The position and orientation in space are arbitrary.
A7

Defines an excitation by means of a voltage gap on an edge between two triangles.

This card has been generally replaced by the AE card.
AC This card reads the geometry and current distribution (possibly for more than one frequency) from an .rsd file created by a transmission line simulation program (for example, CRIPTE or CableMod) or by a PCB simulation tool (PCBMod) or by export with the OS card. The excitation is due to the electromagnetic fields radiated by these line currents.
