Hello I am completely new to this software and electrostatic physics modeling.
When I run FasterCap (with all default settings) , I get the following output which ends in an error message.
Can someone help me figure out what I'm doing wrong, please?
I include the contents of my lst file and all txt files below as well.
output:

Hi User137,
the problem in your file is that you have overlapping panels.
Please be aware and remember that no panel can overlap at all - it is not physical and creates issues in the panel-panel integrations.
It is user responsibility to avoid that in the input file there are overlapping panels.
As an example, in thickslab.txt you have
Q thickslab 0.00000 0.00000 0.00000 0.01057 0.00000 0.00000 0.01057 0.00527 0.00000 0.00000 0.00527 0.00000
that is traslated to +90 in the z coordinate
and in ultrathinslab.txt you have
Q ultrathinslab 0.00000 0.00000 0.00020 0.01057 0.00000 0.00020 0.01057 0.00527 0.00020 0.00000 0.00527 0.00020
that is translated +70 in the z coordinate
So effectively you have two perfectly overlapping rectangles at z=+90
I probably should write it as a big remark in the on line manual, as this is one of the most common mistakes (just check the forum, you'll find many cases of the same issue).
BTW if you have issues, in general, a good strategy is:
1) enable the -v verbose mode
2) remove piece by piece from the list file until you get no error or you get to the shortest offending input file, so you can work from there to understand which definitions create the issue
Hope this helps!
Enrico
