Hello,
I was wondering if there is a way to generate an input file for FastCap and/or FastHenry from a gerber file of a PCB.
Thank you
Hassan

Dear Hassan,

at present, there is not a general way to generate an input file from a gerber file. There are some programs that have been developed for various kind of conversion; I may cite XicTools from Whiteley Research (w*w.wrcad.com), that is Open Source and free, but it is not a general gerber to FastHenry / FastCap/FasterCap converter, but can simulate PCB structures in these solvers. I also remember a tool called PCBParC for Power Electronics, but as far as I know, this has never been released as public. I'm also aware of a program called LayoutEditor, but this is not free, and I never used it, so I cannot comment on its usefulness for the task at hand. For exporting to FastHenry there was also a tool called InductEx, but again this is not free and not open source, however a free version existed with some limited capabilities.

Overall, the best way would be to implement such a converter in open source, possibly leveraging FreeCAD - as this CAD is already being extended with an ElectroMagnetic worbench, its scripting language is Python, and there are already some open source gerber readers that could be reused. If you are interested in sponsoring such an implementation in open source, please contact me privately (details in our "Contacts" page) and I'll be happy to discuss the possible options with you.

Best Regards,
Enrico
