Syntax: C <file> <outperm> <xoffset> <yoffset> <zoffset> [+]
The 'C' element at the beginning of a line defines a conductor. The geometry of the conductor surface is further specified in the file <file>
. The conductor is assumed embedded in an homogeneous dielectric medium with relative permettivity <outperm>
. The relative permittivity <outperm>
can be complex valued, in the format ere-jeim, where ere is the real part of the complex permittivity value, and eim is the imaginary part. The conductor can be translated with respect to the coordinates defined in <file>
by an offset (xoffset, yoffset, zoffset), thus allowing to reuse the same geometric definitions multiple times.
The optional +
argument is used to merge the current conductor with the next one, thus treating them a single conductor. With this option, panels with the same conductor name in different files will belong to the same conductor (see panels definitions for more information about conducor naming).
Example 1:
C cube.txt 1.000000 2.0 0.0 0.0
This input file fragments specifies a conductor whose geometry is defined in the file cube.txt
, embedded in a dielectric with permettivity equal to one (e.g. air), and translated to the position (2.0, 0.0, 0.0).
Example 2:
C cube.txt 1.000000 0.0 0.0 0.0 +
C cube.txt 1.000000 2.0 0.0 0.0
This input file fragments specifies a conductor made of two cubes in free air. It is considered a single conductor since the first statement ends by +
, thus collating the two elements; i.e. the two cubes are considered short-circuited together.
Example 3:
C cube.txt 3.0-j0.02 2.0 0.0 0.0
This input file fragments specifies a conductor whose geometry is defined in the file cube.txt
, embedded in a dielectric with complex permettivity equal to 3.0-j0.02 (e.g. with real part equal to 3.0 and imaginary part equal to 0.02), and translated to the position (2.0, 0.0, 0.0).
