Hi,
HFSS is based on an adaptive meshing algorithm
The user set the frequency, usually, in the middle-uper part of the bandwith
and HFSS will build a mesh adapted to the field structure
The user does not need to create the mesh
since the algorithm will automatically create the optimum mesh...
Hi,
first a boundary/source can be applied only to a surface
and not to a line.
Secondly it seems you decide to use the select by name
select one object and on the right column
a list of all the face will appear
select what you need and then apply the bc you want
Hope this help

hfss examples for waveguide slot antenna
Hi,
what about to use PML instead of radation BC.
Pml are less sensitive to the angle of incidence and allow you to calculate
antenna parametr
Hope this help

one of the advantage of HFSS
is the capability to give the Field distribution
for any power applied to the port
By default HFSS will apply 1W to the port
but you can change this value to any other and see the field distribution
without resolving the problem.
When the field inside the cavity is...
The model you describe can be simulated
I believe there is a mistake in your model
or the port is not correctly assigned...
At moment HFSS is in version 9.2.1
may be you can contact your Ansoft office and get the latest
version of HFSS.

hfss coplanar lumped-gap port
Hi,
for your model
I would draw a rectangle between the
terminal a and b and a rectangle between terminal c and d
Select these rectangle and assign lumped port to them.
Draw impedance and calibration lines from the middle of the edge
on terminal a to the middle...

PML is Perfectly Matched Layer
is a kind of boundary condition alternative to radiation
to be used when you want simulate an open model
(antenna, FSS....)
LBC means Linked Boundaryu Condition and is equivalent to Master and slave
and is used fopr periodic...
exporting from matlab to hfss
you do not need Matlab
for your target
Import the HFSS model in Designer
draw the lumped elemnt schematic you
want to use to match the HFSS results
and use the Optimizer of Designer to find the right vaqlue for RLC

Hi.
not always dense mesh means good results
if you made a wrong setup
you can run it for ever get monster mesh and still not getting good results
but this due to wrong modelization
I would be curious to see your model and your measurement
to see if the accuracy of the simulation can be...
Hi,
when you draw an object you can assign
Perfect conductor to it.
HFSS will consider it a s perfect conductor not as a ground since perfect ground does'not exisit in reality....
and in any case you do not need a perfect ground to create a CPW
exitation.
If you have a legal copy of HFSS and...
Re: Microstrip design at low frequency (868MHZ) : CST or HFS
Hi all,
with the new GUI of version 9
HFSS is now very easy to use
and with its frequency sweep algorithm can be easily used to
analyse broadband structure
In these days I analised an REF Mems
in a range from DC to 800 GHZ
in one...
feko vs hfss
I would not say that HFSS cannot handle
large radiation problem
I could show a simulation results of very large waveguide array
of course HFSS being a professional tool giving accurate results
require a professional machine with professional characteristics
in version 8
Open Maxwell Control Panel
open Utilities
open Plot data
in Plot data you can define any kind of function plot it and export in sm2 format
sm2 format can be imported in any project
either version 8 and version9
