take a look at sfepy.org, its an open source FEM software written in python.

FEAP is an excellent code

FEAP is an excellent code for developers. Much of the heart of the code is transparent kidney stones

heat transfer in porous media

FRZ — Tue, 25 Jan 2011 19:56:36 -0500

Hi
I want to know if there is any feature in ANSYS11 which using it I
can solve a simple direct heat conduction problem for example in a 3-D geometry? All boundary conditions are known, and I want to solve heat equation and obtain nodal temperatures in porous media.
I appreciate if you guide me.
regards
FRZ

For a "all in one" FSI

Karl van Aswegen — Fri, 21 May 2010 05:04:39 -0400

For a "all in one" FSI package look at Elmer:

http://www.csc.fi/english/pages/elmer

I think with Elmer you can do two way coupling between a fluid and structure but I am not sure if this is limited to a steady state analysis. I don't know much about Elmer but by just having a quick look at the documentation it seems like you will be very limited to material, elements etc. but being open source and when using it for research I suppose you can just write your own in Fortran.

You can also do a one way coupling between Code_Saturne and Code_Aster by just reading in pressure boundaries from the cfd run and apply it to your structure. For a static analysis with small deformation this should be good enough. But if you want to make use of the full power of Code_Aster and Code_Saturne + you have a lot of patience + you make use of Google translate (because most of the code is written in French) it is also posible to do two way coupling. I read on the Code_Aster forum that they are currently validating this feature in their labs so it should become easier to set up by the end of the year. I have not tried this as open source FEA/CFD is something I have to do in my spare time because we use comercial FEA at work but unless you can do transient/dynamic FSI to look at flow induced vibration it is kind of pointless to me anyway.

Thanks for this topic.

wonderfull stuff!

Particularly the code-aster. I wonder I got a open source software for FSI.

Hi all, I think

Karl van Aswegen — Fri, 14 May 2010 06:29:58 -0400

Hi all,

I think Code_Aster by EDF is probably the most "complete" free finite element code.

See http://www.code-aster.org/V2/UPLOAD/DOC/Presentation/plaq_V7_GB.pdf for capabilities. You can find English documentation and examples on the CAE Linux wiki: http://www.caelinux.org/wiki/index.php/Doc:CAE

I also use Salome http://www.salome-platform.org/ for a pre and post processor. It is also opens source, easy to use and very powerfull.

Obviously none of the above is more easy to use than a commercial package like Ansys, ADINA, Ls-Dyna etc. but then again it does not cost anything. Anyone that is interested in some CFD every now and again check out these two open source programs.

http://www.openfoam.com/ and

http://research.edf.com/research-and-the-scientific-community/softwares/code-saturne/introduction-80058.html

The downside (or upside for some) is that most of these open source packages are created for Linux. Also all the mentioned programs are validated and actively used in industry.

Regards,

Karl

CASTEM

SivaSrinivasKolukula — Fri, 23 Apr 2010 07:46:58 -0400

Hi all

CASTEM is a computer code for the analysis of structures by the finite
element method. This code was developed by the Mechanical Department and
Technology (DMT) of the French Police station with Atomic Energy (ECA).This is a free FEM software which could be downloaded from the link :http://www-cast3m.cea.fr/cast3m/index.jsp

Actually this is a software in French language but help available in English. Documentation is available in English but vast in French language. It has got many modules and source files (codes) for reference could be downloaded from the site. Complete details about the software are in the above mentioned link.

Inspiration and genius--one and the same.

No Manual!

Hisham — Fri, 23 Apr 2010 04:26:59 -0400

Hallo!

I know that this is an old thread, however, I cannot find a manual in the link of the hp-fem code you've sent! Do you, kindly, know where can one obtain a comprehensive manual for such code?

Thanks,

Hisham

I've been having problems

manincrisis — Fri, 08 May 2009 06:33:20 -0400

I've been having problems with Firefox for a lot of time. but even if Firefox has the 10% share of the people i would still use it.

castem and zebulon

PANIERSTEF — Wed, 18 Mar 2009 17:29:05 -0400

Do you know these 2 other french fem codes Castem and Zebulon?

Castem is closed to code aster and you can find english documentation for this software on the CEA's website .

http://www-cast3m.cea.fr/cast3m/xmlpage.do;jsessionid=2907427F20B5233B2C...

Zebulon is a very good fem codes too with englis documentation but i never use it.

Code Aster

georient — Wed, 14 Jan 2009 19:11:30 -0500

I have been looking for an open source or low cost (<$1500) structural FEM package to support optimization of aerospace structures subjected to thermal loads. For optimization, I have been using genetic algorithm in a distributed processing Linux environment. License cost for our current commercial FEM package is getting prohibitive.

Reviewed all packages I could find here and from other sources. Code Aster is the only package that seems to be remotely close to what I am looking for. Alas, I don't read French...

Does anyone know of English documentation other than that available at the Code Aster site?

Also, have I missed a good package for the aerospace Analyst (per John Dolbow's very appropriate nomenclature)?

Thanks for your collective wisdom; this is a great forum!

Modularity is part of the FEAP design

Sanjay Govindjee — Tue, 23 Sep 2008 04:13:04 -0400

Modularity is part of the FEAP design; if you stick to modifying things through the many user interfaces for materials, elements, mesh commands, solution commands, plotting commands, etc. then you are pretty safe with respect to updates. If you muck around in the internal guts of the code then you need to be more careful. That said, if you do something invasive but it is useful to not just you, but also others, then Prof. Taylor will quite often include your developed features (maybe re-writing them) in the next release of the code.

Say you have modified FEAP,

Achilleus — Mon, 22 Sep 2008 15:38:56 -0400

Say you have modified FEAP, and then next release of FEAP just comes
out. What do you do? Is FEAP modular enough so that you can insert
your modifications right in, from one release to another? As a user,
can you contribute to FEAP? How do you do that?

Thanks

Cris

Hey

oyunindir90 — Sun, 24 Aug 2008 16:46:32 -0400

one of the disadvantages of ELMER is it does not use PETSC and it's ability in solver paralization is limited.

Kodanda,

Thank you for the link to OpenDx. Will check it out later.

What is the status of open source finite element code?

admin — Mon, 20 Nov 2006 16:59:03 -0500

FEMs are widely used in education, research, and industries. What is the prospect of having a vibrant community to evolve an open-source finite element code? What are the potential benefits for such a community and code? Has anybody tried?

Presumably whoever active in this effort may find support from government funding agencies and industries.
