Any circulator guys?
Dealing with a WG circulator.....
I used Uniform magnetic bias before for the ferrites in HFss and got good results. However, in order to get more realistic results and understand exactly how strong the magnetic bias needed to saturate the ferrites, I am trying to use maxwell to generate a "real" magnet bias enviroment (2 permanent magnets and 1 magnetic return), and import this enviroment to my hfss circulator model.
Thus, according to the circulator's postion and dimensions, I built the maxwell model (2 magents, 1 magnetic return, and 2 ferrites between magnets) and could see the magnetic flux density (B) in the ferrites. Then I saved this maxwell files in the same folder of hfss circulator file.
However, when I tried to import this maxwell files in hfss model by selecting "Non-uniform magnetic bias", hfss gave me the following error:
[error] Adaptive solution setup, process hf3d error: Error in creating static solutions from Maxwell.. -- Simulating on machine: hfss1 (2:37 PM Dec 01, 2009)
Does anyone know what is this problem and how to solve it?
Thanks in advance.
No one can help regading this issue?
seems like less guys coming to forum these days.....Still in first page after several days....
All must be preparing for Xmas
This error usually means you have run out of memory in your computer,
and occurs after the mesh, half way into the first solve.
You may need to change the meshing options to reduce the tetrahedra count.
Another brief question: in HFSS, when you use the uniform magnetic field with ferrites, I have found it completely ignores the field strength, but uses the ferrite saturation field indtead! I have seen this behaviour in V9.2.1 and V11: does it work for you?
Hi hughrpg,
Thanks for your reply, but I don't think the memory is the issue. The problem should be the communication issue between Maxwell and HFSS, since I am using a HFSS server (not locally in my PC) to solve the model.
Understand the uniform option, which i used always before. As I mentioned, I want to get more practical/realistic simulation result, thus try to use maxwell to generate the bias.
Thanks anyway.

HI i am also trying to design a circulator .Can you see my file and point out what is wrong?
