Hello,
I am working with this .inp file. This was made by an FH2 generation script that I made, which will be put used with an optimization routine for PCB layout.
When I try to execute this script, the software seems to crash. The FH2 dialogue window opens, displays the preamble, and then it crashes. I am not sure why. Can I get some help troubleshooting this one?
Thanks for your time, and patience with a noob! :)

Hello, I was able to resolve my issue. I believe it was because of two of my excitations(.extern nExc_Via1Node1 nExc_Via2Node1)seemed to be touching each other. I removed the connecting net in the following Code:

Happy you made it. FastHenry should catch the exception in case there is some issue but I'm afraid there are some failure cases where this does not happen.
Most of the time, however, this is cause by some invalid input file. The most effective troubleshooting method is to reduce progressively your input file until you have the minimum offending input.
Then either you are able to understand the issue or you can start FastHenry in debug mode (requires you to compile the SW with debug symbols and attach the debugger; you can do that simply enough from VisualStudio).
Best Regards,
Enrico
