This utility translates a FastHenry input files into FastCap ones.
Every segment is converted into a cube like the ones generated
with cubegen_c, but respecting wx, wy, wz specifications (that is,
segment's spatial orientation is kept). Then segments electrically
connected (also with .equiv statments) and belonging to the same
port are stored together in group files; there will be as many
group files as ports in the source file. A FastCap list file will
include all group file names as well as a comment line showing
the name of the two nodes from which the port is made up in the
FastHenry file.
You can also specify a custom dielectic constant for the homogeneous
medium in which panels are (of course, you have to insert manually
medium discontinuities, because input file doesn't contain such
informations), a edge to inner panel width ratio and a
discretization step. The latter is defined as the maximum length
of a panel's side. Note that segment's end faces are always
removed, except when -f option is specified.
Moreover, you can decide to replace any segment with any other
structure you have defined in a FastCap file; you only have
to specify a string of characters which are included into
the segment's name (you can decide, for istance, to substitute
every segment containing the string 'ball'; then the segments
'ball_1a' , 'bouncing_ball' and so on will be replaced with
the panels described in file you have chosen, maybe 'sphere.neu').
Remember that to the contents of your file will be given an offset
corresponding to the spatial position of the FIRST node of the
segment which is being replaced.
Unfortunately, I was in a hurry when I wrote this routine, so
neither uniform nor nonuniform gnd planes are recognized by
the software (they are simply ignored); maybe later on..


Usage: convertHenry [-n<sourcefile>] [-l<listfile>] [-g<groupfile>]
[-c<dielectric>] [-e<rel edge panel width>] [-d<discr.step>]
[-s<segment name> <file name for substitution>] [-f]

Option Default Function
-n fh.inp Specifies FastHenry source file
-l list.lst Specifies FastCap list file name
-g group Specifies FastCap group files base name
-c 1.0 Dielectric constant of the medium
-e 0.1 Specifies edge to inner panel width ratio
-d 100 Discretization step
-s - Replaces every segment containing the string
<segment name> with the contents of specified file
-f - Do not remove segment end faces
