hi!everyone,i am designing a microstrip filter using HTS.the tranmission band is 2~2.025Ghz.when i use ensemble ,i donnt know whats the value in"adaptive frequency option"in"adaptive analysis option"is proper!and i found that if i change the value in"adaptive frequency option" ,the speed of convergency is also different.sometimes it cannot be convergent when i set the suggested value 0.05 in the"target maximum delta norm(q) option".why?and whats the value in "target.."is proper.
i need some information about these!
thanks in advance!

In my experience, 0.05 is the not a very good value. You may try for 0.005. But it will take longer time. But if you just want get a quick an approximate result then just leave adaptive analysis. Try to go for meshing for maximum frequency or little bit higher frequency for better accuracy. For your case you may choose fixed meshing at 2.5 GHz and leave adaptive analysis.
