Hey! All
Thanks in advance!
Trere are errors ocurring when after run. It is just a simple case that i would like to get the capacitance martix of a copper strips which was discreted into there blocks.
There are my input file and list file.

But it seems can't end with convergence even i can't close the outpu windows.

FastCap2 has no capability to automatically refine the input geometry. The input file you provided is far too coarse.
If you are not willing to provide more discretized geometries (and more discretized again, to see if you reached convergence) I recommend you to use FasterCap, that does have the automatic refinement capability.
Best Regards,
Enrico

FastCap waring and can't stop
