FasterCap 2D Input Files

Straight segment definitions ('S' statement)

Syntax: S <condname> <x1> <y1>   <x2> <y2>

The 'S' element at the beginning of a line defines a straight segment. If the segment belongs to a conductor surface, the <condname> parameter is used to associate the segment to a parent conductor named <condname>. If the segment belongs to a dielectric surface, the <condname> parameter is ignored. The (x1, y1), (x2, y2) 2D points specify the coordinates of the two end points of the segment.

Example 1:
 
S circle 0.1 0  0.098768907 0.015642989

This input file fragments specifies a segment of the surface of a conductor, whose name is circle.

Example 2:
 
S inner_shell 0.098768907 0.015642989  0.095105938 0.030900818
S outer_shell 0.095105938 0.030900818  0.089101283 0.045397812
S inner_shell 0.089101283 0.045397812  0.080902789 0.058777026

This input file fragments specifies two segments of the surface of a conductor, whose name is inner_shell, and one segment of the surface of a second conductor, whose name is outer_shell.
