Yes, that is what I was going to suggest. You can always get Y or Z parameters from the resulting S parameters.J now get sensible answers by looking at the coil admittance with a lumped port.
Thanks, I appreciate you taking the time to respond to my question. I spent my career looking at resonant cavity circuits. It never occurred to me to look at the problem non resonantly. Now I am looking at the affect of this analysis on my results.Yes, that is what I was going to suggest. You can always get Y or Z parameters from the resulting S parameters.
This method of breaking up resonant structures was invented by an EM solver company maybe 20 years ago, to reduce the number of frequency points required to cover a frequency band. One requirement is that port calibration is very accurate. I hope that it works ok for your case!It never occurred to me to look at the problem non resonantly.
As I recall (I no longer have access to HFSS), you can export the mesh from one simulation, and then simply instruct the solver to use this mesh every time going forward.However, HFSS recalculates the mesh when the external capacitance changes even though there is no change in the geometry. To get sufficient precision I need a fairly big mesh. If I could simply keep the mesh from the first value of the capacitor I would eliminate the time to recalculate and reduce the noise that comes from using a different mesh with the same convergence criterion. There seems to be no way to do this, and I can't find any workaround. I'm looking for ideas or a solution. Thanks, Jim
Thanks for the reply. That would be a solution, but I haven't been able to figure how to do it.As I recall (I no longer have access to HFSS), you can export the mesh from one simulation, and then simply instruct the solver to use this mesh every time going forward.
