Hello dpres,
I now got a new version of HFSS. HFSS 13 and finally got it running with Windows 10.
There is a ADK included and I already constructed a LPDA and analyzed it.
I invented a new antenna principle and at the moment I am trying to analyse it with HFSS, since EZNEC gave me slightly...
Hello dpres .... Thank - You for the reply. I saw that symmetry splitting in FEKO once, but didn´t realize it being valid for HFSS also. I will play around with the symmetry settings as soon I have time, at the moment, I don´t have any.
Best wishes, Sebastian, Germany.
Thanks for the link. When I worked at Hirschmann Company, the guys of the automobile section worked with FEKO. Then, I didn´t understand much of it, I just had learned EZNEC and FEKO was too big for me.
Today, I have read the manual of FEKO and know about its working principle. Actually, I...

Ah ok. I am into antennas, I am a physicist with major in electronics and antennas. Usually I worked with EZNEC, but since I want to apply for doctorate scholarship I have to be familiar with FEM solver (FEKO, CST or HFSS). I read a lot about FEKO and know the program from theory, but can´t...
OK, then a 7 el Yagi is not possible to analyse with my machine. Never mind, my goal is to learn the principles of HFSS, so I can use it professionally if i get accepted for doctor scholarship. Learning on Your own is hard. Yesterday I celebrated "basic knowledge" (step 1) with alcohol :grin...
Then, Volker, what is the criteria for FEM models to be "large" and "small" ? The number of wavelengths ? And the resulting number of Tetrahedra ?
Seb.
In general, I would propose using a half wave box (or sphere or cylinder). Lambda/4 is a little problematic in my view (too small). If possible, try (and error) with half wave box. Compare the results. If there is little difference in the S - Parameters (< about 5 %) it shouldn´t matter.
I had...
Ah ok thanks. Now it makes more sense. I used to work with EZNEC Pro (NEC-2) and there a 7 el Yagi is no big deal. It takes some minutes to complete accurately. I see, FEM is a completely different principle. Didn´t realise that. Well, ok, I got quite far with HFSS with my limited resources and...
My computer is too old anyways. A 1500 MHz Athlon with 1,3 GB RAM. It takes ages to analyze. My goal is to learn HFSS not to work with it here.
7 el Yagi ... it is about 70000 tetrahedra by now. Is an example. No conversion yet. I am not really clean with all the analysis, there are still...
Yes I have read about that. The Problem is, that I have HFSS 11 beta and the feature ain´t available yet in that version. There must have been another way in earlier versions.
When i finish a simulation (here 7 el yagi antenna) it tells me "normal completition of simulation". When I apply mesh...
