hfss optimization
Hi guys,
First time to do the HFSS optimization to tune a dielectric filter. I set a goal for S11 in a specific frequency range and acceptable cost is set as 0. Widths of the iris are the tuning variables.
The optimization finished much faster than I expected. I thought I had a super good luck that already achieved the 0 cost accidentally. However, then I noticed that HFSS only tuned 6~7 iris dimension variables, and then stopped. The minimum cost is only 0.4.
In HFSS->Design Propoties->OPtimization, I can see the Min and Max of the tuning range for the variables, but my question is how I can set the "tuning density"? (Sorry for my English, I mean how I can make HFSS tune the dimensions by changing them little by little?)
Thanks guys, I already searched the posts relating to this topic, but couldn't find the clue. Also, could any friend send me some tutorial regarding HFSS optimation?
Appreciate any help.
Regards,
Lee
