    Re: FREE electromagnetic simulators, rather than commercial ones

    No. Not all. All MIT packages are linux compatable.

    Re: FREE electromagnetic simulators, rather than commercial ones

    can anyone suggest me a software to simulate an electric charge (coulomb) in cylinder or globe shape?
    i want to see electric and magnetic fields of these structures.
    Thanks an advanced.

    Please go through the following link.
    Physics Flash Animations
    Will post more as and when they are available.

    Hi tyenergy,

    I am studying the mode-matching method for multiple layers electromagnetic problems. Now I mainly refer to the following two papers:
    1) Guo-Xin Fan, etc., 3-D Numerical Mode-Matching (NMM) Method for Resistivity Well-Logging Tools
    2) Zheng Lou, Waveguide Filter Design with Finite Element Method and Mode Matching

    The first one gives more detailed information on the mode-matching method but only focus on the Possion's equation. I wish it also works for the Helmholtz's equation, so the second one is a good reference.

    However, I still can't have a good program to realize it (in fact, I haven't got all details in both papers), could you please share me your code for my study?

    Thanks

    Re: FREE electromagnetic simulators, rather than commercial ones

    Hi all!!!
    Greetings from Brazil!!!
    Eng.amq I has downloaded the source code but I cant compile it on my Ubuntu 10.10...
    Can You help me please???

    Thanks in advance and Best Regards,

    Silva.

Knowledge should be FREE for everyone in this world..

    I'm an open-source software fan and would like to share my interest here to get some beneficial replies for me and the others as well.. so please guys help me in listing what you know about FREE magnetic, electrostatic, electromagnetic, heat flow, current flow, whether full wave 3D simulators or not.. even if codes executed in MATLAB or C/C++ or anything else. Help the ones who have brains but no money to do research and innovate this "money and business oriented" world. Let's encourage the volunteers who are working to make these things free for us, their efforts are really cherished..

    The first and best one I know is emGine, you can download it from http://www.petr-lorenz.com/emgine/
    It can be used to simulate 3D structures using FDTD method. The software is still very young and needs many stuff, yet, it works just nicely. Here are some screen shots:

    Anybody knows anymore? especially in the field of Antenna design, planar structures design..

    Re: FREE electromagnetic simulators, rather than commercial ones

    Hi.
    Am very bad operating computers, loading/operating new programs and am running Linux.

    Is there an expert in any magnetic simulation program that can create a simulation of this concept, by showing the fields magnitude/direction in motion? :

    If it is too much asking for someone to 'do my homework' (which is not; just curiosity), am sorry, thanks for your patience.
    Abolish the deciBel !

    Re: FREE electromagnetic simulators, rather than commercial ones

    Hello people,
    It is very nice to see so many freeware available.
    Thanks for sharing!

    I also want to contribute a bit.
    Please find a software named EMANIM, a free software that lets you visualize EM wave propagation through free space and some dielectric, polarization effects and much more. Find it here, and use it to understand EM theory concepts in a better way:

    Thanks and Regards

    It's a very cut-down version which is free. The full version is far from free, and a waste of time in my opinion.

    Re: FREE electromagnetic simulators, rather than commercial ones

    openEMS

    http://openems.de/index.php/Main_Page

    which is based on the FDTD technique looks intersting. It uses MATLAB or the free Octave clone as a GUI.

    I've not used it myself

    You may try FEKO as well. They have Linux compatible versions and an evaluation license can be downloaded for 3 months free of cost.

    Re: FREE electromagnetic simulators, rather than commercial ones

    I have found a new good free antenna tool, called QAntenna. It is dedicated to viewing and analyzing antennas and their radiation patterns. It provides the user with a 3D view of the models, capable of zooming, and rotating. You can find it here: http://qantenna.sourceforge.net/

    Dear Silva,

    Pardon me for the super duper late reply, I've not been coming here lately, but I'm hopefully back again.

    Regarding your question, you can follow the link below, to teach you how to compile source-code packages, and install them on Ubuntu. It's easy, especially if you have all the dependency list available/installed in your system.

    http://askubuntu.com/questions/25961...r-tar-bz2-file

    If you still can't find it helpful, I found a very comprehensive and easy to follow Youtube video. It teaches various ways to install software in Ubuntu: http://www.youtube.com/watch?v=toO-WbLppl0

    All the best! (though I think you have installed it and even mastered it )

    Re: FREE electromagnetic simulators, rather than commercial ones

    are there any free Sensor Unit simulator (or even not free like Multisum for designing circuits) just i need it for designing a sensor unit not an electronic circuit where i can find the transceiver, microcontrolars and other equipment needed for the design ???

    but the application won't open
    I just found this file --->> err_emGine.txt

    sys.stdout = <__main__.Blackhole object at 0x025145F0>
