Hi Chand,
Usually for smooth transition, I will use interpolation sweep. Fast
sweep is preferred in highly or multiple resonances cases. Of course,
you can always to run discrete analysis to verify.

Subject: [SI-LIST] Problem with HFSS 9
Hi everyone
=20
I am trying to get impedance plots for a power bus board using HFSS 9. I
performed simulations on the same geometry using the following 2
frequency ranges:
=20
1) start =3D 1 MHz, stop =3D 200 MHz, step =3D 1 MHz
2) start =3D 1 MHz, stop =3D 1 GHz, step =3D 1 MHz
=20
But the impedance plots (1 MHz - 200 MHz) are different for both cases.=20
=20
Can anyone let me know the reason for that. I am using "fast" frequency
sweep.
=20
Thanks
