Posted - Sep 23 2010 : 09:19:35 Dear all,
As I am using FastHenry for simulating coil structures, something suprised me when I started using the tool: there is no port definition. I mean, in a MoM/FEM simulator, you decide what kind of excitation is applied "here", and "there", with a nominal impedance (somewhat 50 ohms). So, is there a need to specify port impedance with FastHenry, or is this a misunderstanding how simulation occurs ?
Hope you could help me.
Best Regards

(at a frequency near 0Hz) Fundamental rule says R = rho * A /l you would come up with the same value without definition of a port. You also could see it as Voltage drop occuring from a current of 1A.
Hopefully that is what you where asking about, otherwise I'm sorry
