What is the best 3D EM simulator?

Manju:

I think that the Sonnet broadband Spice model exports for Cadence Spectre and Pspice formats. I think their Pspice format also works for Hspice.

You can load any S-parameter data set into their broadband Spice extractor; it will even extract for a measurement data set. The source S-parameter data set doesn't have to come from Sonnet's EM simulator.

selecting 3d electromagnetic software

hello,everyone!I am a newer.Could you tell me where Ican free download the HFSS ??Thanks

Hi Max,


Yes, but HSPICE accepts in *.sp or *.inc spice netlist format, & I don't know whether such files are generated from that conversion...

Even standard PSICE format *.cir format also may not be generated...

free em simulation software

not good to ask free hfss. the software is good and has its value.

true that selecting a 3D EM solution is related to your application, time you have to perform your study.

knowing quite a few, the one giving me good results is MICROSTRIPES that employs the Transmission Line Matrix (TLM) method to solve Maxwell’s equations in the time domain.

The TLM method time domain solver is accepted as being the most computationally efficient and inherently stable.

MicroStripes is ideal for solving extremely complex and electrically large problems.
spectrum of applications including Microwave and RF devices, antennas, Connectors, Numerical Dosimetry (SAR), High Frequency IC’s and package design as well as lightning strikes.

best mom em software

Hi Dear coniglioe!

I myself use HFSS for radiators and 3D structures and I belive it is powerful enough to help, and use Maxwell control panel for 2D low frequencies structures.

Thanks!

Don't forget the Micro-Stripes Release 7.0
Flomerics Limited
flomerics.co.uk
It is based on TML,and fast than CST and HFSS.

ie3d maxthread feature

The XFDTD 3D EM solver from Remcom (State College, PA) also is based on the FDTD method.
This solver also provides support for the new female body mesh. Should greater precision in the human body be required, Remcom recently developed high-fidelity human meshes for both full-body (male and female) and head/shoulders regions. All three meshes can automatically adjust the permittivity and conductivity of the tissues for any specified frequency between 1 MHz and 20 GHz.

Is it possible to export XFDTD human body model from XFDTD to CST or HFSS?

the EVAL.ZIP file. Please unzip it into a temporary directory to get
the setup files which includes this README.TXT file. The price list
is in the PRICE_LIST.DOC file (for domestic users) or the
PRICE_LIST_INTERN.DOC file (for international users).

4. Please run the SETUP.EXE in the directory to install the software.
If you are using WINDOWS NT, 2000, or XP professional, you should
login as administrator before you run the SETUP.EXE.

5. After installing the software, please restart your computer to let
the DLLs and driver take into effect.

6. After the computer is restarted, please run the ZELAND PROGRAM
MANAGER (ZELAND.EXE or ZPM) from the ZELAND FOLDER.

The ZPM will try to connect to our server. Please make sure your firewall
will not block the access. On the latest evaluation software, the ZPM or
ZELAND.EXE is renamed as EXPLORER.EXE in order to avoid blocking by
personal firewalls. However, network based firewalls may still be able to
block the ZPM renamed as EXPLORER.EXE. In case your connection is
blocked by your firewalls, please contact you system administrator to
un-block our ZPM if possible.

To use the evaluation software, please do the following:

(a). RUN ZPM from ZELAND FOLDER. If you can not find it, you can run
it from the directory: c:\program files\Zeland\exe
(b). ZPM will prompt you the SPECIAL NOTES FROM ZELAND SOFTWARE, INC.
Please read the terms in the notes carefully. If you agree to
the terms in the dialog, please check: I agree to the terms.
Please select CONTINUE to go ahead. If you do not agree on it,
you should select STOP.
(c). ZPM will prompt you for the LOGIN. Please type in the USER NAME
and PASSWORD you received from ZELAND SUPPORT from e-mail.
(d). If you type in the correct USER NAME and PASSWORD, ZPM will

there is any alternative way to access and evaluate our products.
(b). In case you are able to connect to our ZSS server. However, very
soon, your ZPM will stop the license. You will notice a message
indicating that "Your ZSS/ZPM are detected to be invalid..." on
the ZPM. It is quite likely your ZPM is outdated. You need to
contact us for an updated ZPM.
(c). It is possible that you may see the message "Your ZSS/ZPM are
detected to be invalid..." even using the updated ZPM. Such a
problem can be from a special setup on Microsoft Internet Explorer.
Please try the following to see whether you can resolve the
problems:
1. Start Internet Explore
2. Select Menu Tools -> Internet Options -> click Connection tab
-> click LAN Setting button.
3. We assume that the check box in the Proxy server group box is

weakness of sonnet electromagnetic software

FEKO..FEKO is a full wave, method of moments (MoM) based, computer code for the analysis of electromagnetic problems such as:
EMC, shielding, coupling, antenna design, antenna placement analysis, microstrip antennas, and circuits, striplines, dielectric media, scattering analysis etc.
FEKO includes the Multilevel Fast Multipole Method (MLFMM) which is an efficient method for solving electrically large problems using the accurate full-wave (MoM) technique, but requires much less memory than the conventional MoM.


The MoM has been hybridised with asymptotic high frequency techniques, physical optics (PO) and the uniform theory of diffraction (UTD). This true hybridisation reduces the computational resource requirements, enabling the analysis of very large problems (e.g. antenna placement analysis).

The MoM/FEM (Finite Element Method) hybrid is a very efficient formulation for the analysis of inhomogeneous dielectric bodies

HI friends,

What free or commercial simulator I can use to simulator electrically-small antennas at low frequencies (140-180 kHz).

Thank you all.

HI friends,

Thank you all.

What kind of antennas?

If they are planar (flat, with possible use of vias), there is a free version of Sonnet that you can use (I just saw a post where you can combine MATLAB and Sonnet Lite to get optimized patch antenna designs). Just google Sonnet Lite. There are also evaluation versions that you could get from the various vendors out there.

If your antenna is not planar, then you can't use a planar simulator. I recommend that for antenna design, you look for a time domain code (like FDTD, TLM or FIT based code); they are more efficient for large space problems like antennas than finite-element codes--especially if you need broadband performance.

em simulator 3d

The antenna ITSELF is 3D but can be simplified to 2D to save sim. time.

However, I'd like to simulate 2 antennas together in space. So although I simplified the antennas to 2D, I will simulate them at various positions in space, therefore I think 3D is required, correct me if I'm wrong.

costox:

If the antennas can both be simplified to planar, and if they are both on planes that are parallel, then you can use a planar EM solver. If they are separated by some distance, then the planar solver would probably be all the more efficient, since you only mesh the metal traces and not all of the volume of the problem.

However, if either of the antennas is tipped so that their planes are not parallel, then you need a full 3D approach, I think.

Good luck,

--Max

ie3d free download

I agree with you that 3D is likely required.

The possible scenarios are:
1) antennas are not in the same plane (i.e.: one in horizontal, the other vertical plane).
2) antennas are horizontal but at different floors (as in a building)
3) antennas at different angle in 3D space.
4) etc, etc...
