#12 questionable output from calcCAP

[Dan McMahill]

Again, I don't know if this is a pilot error, but I'm
noting that for a 50 mil wide single microstrip trace
over a 10 mil thick, er=4.8 dielectric with a ground
plane underneath, calcCAP gives a capacitance of
1029.14 pF/m and Estimated Maximum Computational Error
is: -0 (zero ?!). However, by my estimation, I should
have something more like 269.3 pF/m which is off by a
fairly large amount. Also, the output file doesn't
actually say that the units are "pF/m", I decided that
must be what it is from the source code.

With the 2 wavelet simulators, are there any parameters
which should be used to control accuracy?

The BEM routines seem to agree fairly well with various
check calculations I've done.

This is a nice tool. Thanks for making it available.
