HFSS graph output never changes

Hi all,

I'm trying to do the dipole antenna tutorial on HFSS as found here. (click under 10/18/04, HFSS Training Tutorials; HFSS file and pdf of tutorial attached in zip file).

I've followed every step very carefully and am able to get something that looks like the graph on page 23 of the tutorial (the "v" shaped one). The only difference is that the tutorial's graph's minimum point is at -14.5 dB while mine is more like -15.5.

A bigger problem is that NO MATTER WHAT I DO TO THE PARAMETERS of the system, I cannot get the graph to change to the one on pg. 24.

I have changed the impedance as instructed in the tutorial, no change. I have even sent the impedance up to 1000 ohm to try and see SOMETHING change, but I always get the SAME graph as in the previous part. Identical.

Does anyone know why this might be happening? Some help would be really really appreciated. (pleasepleasepleasepleasethankyouthankyou....)

Thank you all in advance,

If you are using hfss9.0, try deleting the graph and creating a new one. It's a bug in the software.
