adaptive steps in hfss
Hi,
I am new in HFSS and I experience the same problem size difficulties. In a recent post I had shown my problem geometry:
**broken link removed**
**broken link removed**
The dielectric substrate is in square form. (6λ*6λ)
Thickness of the substrate is th=0.1λ
Height of the airbox is 1.0λ (airbox also contains the substrate)
Operating frequency is 30GHz, (λ=1cm)
The infinitesimal dipole length=0.02λ, width=0.002λ.(+z directed 1A current excitation is used along the dipole)
In this problem at adaptive pass#7 I get the famous " Adaptive solution, process solver : Insufficient memory for subprocess "%3" " error. And execution stops.
In reality I need to increase the width of the substrate up to 15-20λ. Now I'm step by step trying to increase the problem geometry and try to see what happens.
Now what do you advise me? I use automatic meshing of HFSS and don't do any meshing operations. I sure need to manually adjust mesh properties but have no idea about how to adjust these mesh properties. Any material on mesh adjustments is welcome.
On the other hand, as far as I know, I may use a symmetry plane etc. but again have no idea about how this is done. So again I need some good sources about these thing.
Finally, I don't know how to adjust the Analysis setup, how many adaptive passes are actually required, which delta S (E) gives acceptable nearly accurate results.
It seems to me that these kind of important keypoints or tricks will take time to learn, so i will be very glad if you share your ideas.
I'm also attaching the Solution data (convergence plot) and the HFSS project file.
Thanks again... :|
