Hello,

I am trying to find the self-inductance and mutual inductance between identical coils.
I define the coil coordinates using Matlab and copy+paste the input file to FastHenry2.

More often than not I get an Internal Warning or an error like below:

Internal Warning: distance d between filaments is negative and large compared to R3sq (d=-0.00000 R3sq=0.000117)

or

uh oh, segs don't seem parallel -0.00156495

This is the input file:

*2 3D Rings with 1 loop elements Lv=5mm Lh=10.8mm (Single Sided PCBs)*

.Units mm

The warning/error keeps appearing for a long time, sometimes I eventually get the R+jL matrix and sometimes it just keeps showing the warning/error that I close it myself using the task manager.

Could you please help me by having a look at the input file and advising me why I get the warning/error?

Thanks in advance,


Hanan

Hi Hanan,

looks like you ended up in some corner case. In these cases, you should strip the file to the minimum input text triggering the error. In our case, it may be for instance:

*2 3D Rings with 1 loop elements Lv=5mm Lh=10.8mm (Single Sided PCBs)*

.Units mm


N1dl1 x=10.9018 y=12.2083 z=0
N1ur1 x=0.92388 y=16.3413 z=5
N1ul1 x=10.9018 y=12.2083 z=5
N1urc1 x=4.98895 y=14.6575 z=5
N1ulc1 x=6.83671 y=13.8921 z=5


E1ul1 N1ul1 N1dl1 w = 1.0 h = 0.5 nhinc = 1 nwinc = 1
E1urc1 N1ur1 N1urc1 w = 1.0 h = 0.5 nhinc = 1 nwinc = 1
E1ulc1 N1ul1 N1ulc1 w = 1.0 h = 0.5 nhinc = 1 nwinc = 1


.external N1dl1 N1ulc1

.freq fmin=1e+07 fmax=1e+07 ndec=1

.end


You may see now that a minimal perturbation of the input geometry solves the issue. For instance, if you replace the N1ulc1 statement with:

N1ulc1 x=6.83671 y=13.892 z=5


where the only difference is 0.0001 in the y position, you can se that the error does not appear anymore.
This would be a valid workaround. We are anyway looking into the ultimate cause of the issue. Similar problems had already been fixed in the past, and were caused by special relative orientation cases hitting singularities in the internal formulae.

Best Regards,
Enrico
