I am trying to find the mutual inductance between a PCB coil and a conductor.But I keep getting the error.
zero element request in file `induct.c' at line 1720
MattAlloc: Couldn't get space. Needed 0

I made the PCB coil using FREECAD part and then used FHPath object to convert it into Freecad.Attached is the code from fasthenry input file.
* FastHenry input file created using FreeCAD's ElectroMagnetic Workbench
* See ht*p://w*, ht*p://w* and ht*p://

Hi Sambeet,

you still need to respect FastHenry rules. In particular, the segments are not connected together only because they touch.

In your file you have disconnections, e.g.

* Segments from paths
EFHPath0 NFHNode001 NFHNode002 w=0.2 h=0.2
EFHPath1 NFHNode002 NFHNode003 w=0.2 h=0.2
EFHPath2 NFHNode003 NFHNode004 w=0.2 h=0.2
EFHPath3 NFHNode004 NFHNode w=0.2 h=0.2
EFHPath0010 NFHNode006 NFHNode007 w=0.2 h=0.2

In this excerpt the
is not connected to any other segment. The paths are therefore not closed. This is not permitted in FastHenry.

Please also note that these two segments

* Segments
EFHSegment NFHNode202 NFHNode200 w=6.0 h=6.0
EFHSegment001 NFHNode201 NFHNode202 w=10.0 h=6.0

are huge w.r.t. the paths. FastHenry will not automatically refine your geometry (except breaking long filaments in shorter segments). If you do not use a more refined / more granular shape the simulation may converge but I would not trust the results.
