Hi, I expect the resistance of a wire to increase with frequency. But I did not see this effect when I test several frequency on a square strip of dimension close to its skin depth.
Is the skin effect not modeled?
Thanks |

Yes the skin and proximity effects are fully modelled.
Actually, FastHenry completely solves the Maxwell equations in the magnetoquasistatic regime, so the only limitation is the minimum wavelength in the harmonic spectrum of the stimulating signal versus the maximum geometrical dimension of your structure.
You probably had not discretized enought your segments into filaments. Please check the user's guide with particular attention to the section discussing the skin depth (I am assuming you have not read it, otherwise you would not have had doubts about FastHenry capability to simulate the skin effect).
Best Regards,
Enrico

Same problem as op and I have lost my user guide. Is there one available online? |

You can install the FastFieldSolvers bundle, the guide is there. The easiest way to access it is to open FastHenry, launch the embedded online help, and in the main page, in the bottom part, you can find a direct link.
