Press to coordinate buttons in the top bar. HFSS is really stupid when it comes to coordinate systems, you sort of have move the axis manually or type in the coordinates that makes 45 degrease turn.
If you have the possibility then use CST MWS it is better and more user friendly EM solver.
I am new in HFSS and I'am working with the eigenmode solver.
1) Which buttens must I press to get a menu that controls the mesh settings?
2) I am simulating a resonator inside a cavity. How du I shape the resonator like a cone?
3)When I have done an eigenmode simulation I would like to have...
Re: resonators
Hi,
A filter is build by resonators. E.g. a combline filter can contain several resonators. A resonator resonates at certain frequencies related to a wavelength.
homomorphic filter using matlab
I'm doing a tunable combline filter. with six resonators. I'm can't do any optimisation in cst it's too time demanding.
I know that it is a little late to add something to this thread. but I'm also building a filter in cst 2006 and I also have problems with simulationtime and accuracy. I can't tune the filter in CST since each calculation last 24h or more. I have heard that some people uses MATlab togehther with...
CSTs transient solver is based on Finite Integral Technique (FIT), and I know more or less how that work. But Comsol uses another technique called Finite Elements Method (FEM) . How does FEM works, and how accurate are FEM compared to FIT?
and also what technique does ansoft use in their HFSS...
Re: Req: Data on EM simulation speed using Intel quad-core C
When you have tried simulating with the processor I would like to see the log files, to see how fast your simulation was, compared to the number of meshcells. I'm working on a high resonating filter structure and I really need some...
The reason is that the frequency solver ( Fast MOR) is normaly much faster than the transient solver, but the MOR does not support TST cells. So if you have a model ( like I have) which contains very small mesh cells I can only use the transient solver because I need the TST cells to get an...
How small should the dimensions of a model be (compared to the wavelength) before one must include TST cells in the calculations? it is only the slow transient solver that supports the TST cells not the fast MOR solver.
yes I have tried the F solver but only on a trail licence. The AR filter for the transient solver works in some cases but not in this one.:cry:
my simulations last very long time and my pass band is attenuated 100dB...
Has anybody any idears or is cst simply not suited for high resonant models?
