Posted - Feb 02 2022 : 22:37:54 Lets say I have a 1x1 square dielectric. The bottom left point is at the origin (0,0). In the top level file I reference this square but offset it to (5,5) like below.
D square.txt 1.0 3.5 5.0 5.0 xref yref
I want the inside of the square to have the dielectric constant of 3.5. Would xref & yref be something like (5.5, 5.5) or (0.5, 0.5) to reference the inside of the square.
Hopefully this is understandable and a simple answer can be given.

If you have a 1x1 square dielectric and you offset it to (5,5) as per your example:
D square.txt 1.0 3.5 5.0 5.0 xref yref
for (xref, yref) to lie within the square you must specify it as e.g. (5.5, 5.5).
This is what I meant saying that the reference point is not translated / offset.
Hope now is clear! Cheers, Enrico

Yes, the question is understandable and the answer is in the FasterCap online help:
quote:More specifically, the reference point is assumed to lie on the <outperm> side of all the panels in <file>. The optional - argument indicates that (xref, yref, zref) instead lies on the <inperm> side. The reference point is not translated, i.e. the offset only applies to the elements specified in <file>.
Best, Enrico
Thank you Enrico for the reply.
Yes I've read the online help and read that specific excerpt as well but I'm too dumb to understand it and it has confused me. So thats why I posted this question. It would help if you could clarify if it is the former or latter xref & yref coordinate pair that would give the correct inside permittivity.
