## Calculating phase velocity of TM01 mode in HFSS driven model

Hi, I'm trying to plot the phase velocity of the propagating TM01 mode in hfss. I'm using single frequency, and according to numerical analysis, the structure should change the phase velocity along a line (for example, z-axis). Any ideas on how to do it? Thanks!

## Array setup in hfss

I designed a 2*2 microstrip patch array...i dont know how to do array setup, radiation sphere setup & analysis setup for array using hfss...somebody clear my doubt

## [HFSS] Calculate the loss inside the waveguide

If you have electronics desktop 17, 2D extractor seems pretty good for doing this type of solving. If you're just using regular hfss, a scattering analysis should give you a good indication of how much power is lost for your excited mode(s).

## periodic structures and excitation (CSTor HFSS)

Hi Shekoofeh, Scattering parameters really only make sense when used to analyze finite arrays. The larger the array, the better, but obviously there are practical limitations. Without using finite arrays and scattering parameters, you'd need a different analysis method. Try looking into Floquet ports in hfss -- they allow you to extract scatterin

## how to build a Archimedean Spiral antenna model in HFSS

I would use the parametric curve drawing feature in hfss to create the particular spiral and then sweep a small circle along the curve to create a wire object for additional analysis. You can create a wide range of 3D lines using this feature but it takes a bit of work to understand how to use the feature. It also sometimes gives strange results

## Discrepancy between simulation results for S-parameter file

Hi I'm not entirely sure if this should belong in this subforum or one related more to circuit simulation, but here goes. I simulated a structure in hfss and was able to export an equivalent *.s4p file so that I could use it in Cadence Virtuoso. However, when I run port analysis in Cadence, the resulting s-parameter simulation is different. I

## Import of model form HFSS to CST and Boundary conditions

Hi I am working on wakefield analysis in a Multi-Bunch Normal conducting FEL Structures. For this I used hfss for modeling as I wanted to plot Dispersion Curves for all cells so I used master slave boundary condition. Since there is no specific tool in hfss for wakefiled analysis so I imported the model in CST Wakefield (...)

## Wake Filed Estimation Using HFSS

Hi Is it possible to use hfss for wake filed analysis of multi bunch constant gradient normal conducting structures? I have used PIC solver of CST for this type of analysis but want to do wake filed analysis in hfss

## RF MEMS Shunt switch analysis

hi can anyone help for simulating rf mems cpw shunt switch in ansoft hfss for obtaining S-parameters. How to analyse the S-parameters for the switch during ON and OFF condition of the switch. Thanks

## matlab code for rectangular microstrip patch antenna and hfss software request.

Hello friends, am designing a rectangular microstrip patch antenna. I used transmission line method to calculate the parameters but need software for other analysis.Please, let someone help me with the matlab code and hfss Software. Thank you for your quick response. Mathson

Yes, that's a lot of points for a regular PC and that will take time to finish. I use a server farm for jobs of that size and larger. Usually, I'll use 8 cores and 16GB to 64GB of memory for jobs requiring hundreds of thousands of tetrahedra. One thing I noticed is that it says "N/A" at the 6th adaptive mesh. Did you stop and start this mo

## ANSYS EDT 2015 HFSS HPC HFSSCOMENGINE hanging on Linux

Folks, I'm using ansysedt on RHEL with an HPC pool license. I am simulating an hfss model (driven) across a parametric sweep. The analysis is utilizing the direct solver with an interpolating frequency sweep. The analysis configuration is utilizing 40 cores with 10 tasks on the local machine (48 cores on this machine). The Job (...)

## [HFSS V14.0] How to match lumped ports?

Hello everyone. As a small test of the effect of port shape and size on their value, I've built a simple current loop of random dimensions with a capacitive element to make it a resonant structure at 128MHz. Looking at the eigenmode analysis result it behaves like it should. However, when I want to inspect its frequency behavior through a lumped po

## RF MEMS switch s-parameters analysis,current distribution stude in ON & off state usi

Hello, I have design the Series ohmic RE MEMS switch in Coventor V-8 and that structure imported on hfss. I am phasing problem in assigning properties such as voltage and then boundary conditions. How to analyse the S-parameters for the switch and then how to design ON and OFF condition of the switch and obtained the current distribution for th

## [HFSS V14.0] Nr. of triangles per defined surface.

Hello everyone. hfss-14 can show the number of tetrahedra per object progressing while performing adaptive analysis. However when I use lots of surface elements (ports, ideal conductors, etc) I am more interested in the number of triangles defined on a surface element. Especially when I suspect the number of tets is running away because the solv

## Simulation of two monopole antenna

Hello, i succed to simulate two monopole antenna in hfss but i dont understand the simulation results because i m beginner in hfss: The difference betwen S11, S22; S21 and S12; RF books will teach you about S-parameter.

## [Moved]: HFSS adaptive passes happens sometimes, and ...

I am working on hfss designing of patch antenna. Here in the design when it is simulated it sometimes completes adaptive pass and does the analysis but the same design if I close and open and re validate and run then it shows conversenge problem. Again if I save the file in some other directory then sometimes it passes sometimes it doesnt.What is t

## HOW to couple ansys and HFSS for thermal analysis

You have to properly set the hfss simulation into Ansys Workbench. Then you re-run the hfss simulation, and you have to link the results with a Thermal (Steady State or Transient) module in Workbench. Once you have imported the dissipated losses into that module, you can easily get the temperature results. However it is not easy to properly set the
