Posted - Oct 05 2020 : 12:55:20 Hello together,
after a while I am once again working on my PCB conversion tool to FH and FasterCap. I created input files like I saw in this post (w*w.fastfieldsolvers.com/forum/topic.asp?TOPIC_ID=952), but FasterCap is not converging. It even looks like the results are getting worse with each iteration.
I am trying to model two wires of copper an top of a PCB and one GND-plane on the bottom of the PCB. Dielectric constant of the PCB is 4.
I hope you guys can help me.
The input files are:

Posted - Oct 19 2020 : 15:31:30 Hello again,
in the meantime I found a small typo in the D-file. After correcting that mistake (the plane wasn't correctly closed), FasterCap still doesn't converge.
So I double checked each point and renamed the conductors (instead of naming each of it "1" as the last time). Also I separated the D-file into Top, Bottom, and Sides like in the microstrip-example I appended in my last post. I put the reference point for the dielectric on the outside (and left out the "-"-argument).
And still FasterCap does not converge. Simulating it without the dielectric results in an answer in a matter of seconds. But when I include it, it looks like the results are getting worse with each iteration.
I hope you guys can help me with that. Maybe I just missed an important point in the documentation.
