I believe I have found a typo in one of the 2D FasterCap input examples.
In the file
.\FasterCap\Samples\2D\three_line_bus_2d__single_file.lst, line 66 appears to contain an error.
The distributed example currently reads:
S diel 0.0175 0.0 0.325 0.0
However, the correct value should be:
S diel 0.0175 0.0 0.0325 0.0
The original version of this file used the smaller value, and the larger one causes convergence issues, as expected.
The same issue also appears in the file diel2_microstrips_0.035.txt, where the middle segment is:
S diel 0.0175 0.0 0.325 0.0
and should instead be:
S diel 0.0175 0.0 0.0325 0.0
Please let me know if you agree with this assessment.
Many thanks for keeping this excellent tool available as freeware—it’s a great utility. |
