I have an .sNp file exported from HFSS, and I can usually import them into MWO without any problems and use them as sub circuits etc.
However, when I had a larger .sNp file (18 ports) I was not able to import it. It did not even show up in the browser when looking for the files.
Is there a...
HI All,
I have been using HFSS for a couple years bgut never have tried tuning variables in HFSS, such as the length and width of a dipole. I have the newest version (12.1) but am not sure how to setup and obtain a useful tune. The Ansys guys did a demonstration of version 12 executing a tune...
So I keep hearing talk of 3:1 bandwidth or something similar at work but have no idea what that means. I know that they can use the formula below and get a percentage. But where does the Ration come from?
(F2-F1)/Fc = BW(%)
% or Ratio
5 or 1.05:1
10 or 1.11:1
20 or 1.22:1
30 or...
Hey All,
I am trying to use the Derivative option now available in the new version of HFSS, has anyone yet used this? I was at a conference with some guys from Ansys and they were running it and showed us all the new great things, the derivatives on the same curve with their own y-axis scale to...
Hi All,
Very stupid question, but usually I refer to bandwidth (in school) as say 25MHz-100MHz. When at work it's always 6:1 or 9:1 or 2.8:1 etc. How is this defined? how can you look at a graph and just see it? I attached an image can you explain its BW?

meshing failure
Hey All,
I am trying to run the most simple simulation ever: a vacuum box with master/slave boundaries on the walls and one floquet port at the top. This will be used as a reference for other purposes. I was able to run and buiild quite easily yesterday and then today my...

Hey all,
I am trying to run MWO to optimize some parameters and I was hoping someone might have a tutorial on this to help me do it correctly and alot faster than I have in the past?
I want to optimize Sparameters and VSWR.
Thanks for your help ahead of time!

import iges into hfss
I also found it impossible to change dimensions (except for scaling the whole object) when importing pro-e files. The problem I have with importing is that when I run my simulation there seems to be a nagging mesh generation error requiring minor surface repair, and then I...
minimum radiation box size hfss
Hi All,
While I also use the same lambda/4 @ the lowest frequency for my RadBox spacing, I also like to break it into bands to make it more computationally realizable. For instance if I were to simulate across 5GHz-20GHz I may take the 5-10, 10-15, and 15-20GHz...
Re: Gain Enhancement
A nice little tool I like to use is Microwave Office which will allow you to import your design variables in an .emp file and then run an optimization on them, this will be much faster than changing geometry and rerunning every time. For instance, I used it to optimize my...
Hi all,
I tried opening a model and was able to do so successfully but everytime I analyze it I get the follwoing errors:
Communication failure. System error no: 109, error description:Unknown error
Communication failure. System error no: 0, error description:No error
Adaptive solution setup...
Hi all,
I am using a colleague's model of a bowtie antenna with a parasitic layer on top. Can anyone tell me what the purpose of this layer may be and how to recognize if I should try using one or not? thanks in advance.
