I am pleased to announce release 2009.4 of SfePy.
Description
SfePy (simple finite elements in Python) is a software, distributed under the BSD license, for solving systems of coupled partial differential equations by the finite element method. The code is based on NumPy and SciPy packages.
Mailing lists, issue tracking, git repository: http://sfepy.org Home page: http://sfepy.kme.zcu.cz
New documentation site: http://docs.sfepy.org/doc
Many thanks to Logan Sorenson for the new documentation contents, and Vladimir Lukes for setting up the server.
Highlights of this release
- unified handling of user-defined functions (for defining subdomains, heterogeneous material properties, boundary conditions etc.)
- greatly improved postprocessing and visualization capabilities, namely:
- support for file sequences (evolutionary simulations)
- animations (using ffmpeg)
- automatic scalar bars
- sfepy_gui.py: Mayavi2-based GUI to launch simulations
Major improvements
Apart from many bug-fixes, let us mention:
- quasistatic time stepping
- graphical logging:
- dynamic adding of data groups (new axes) to Log and ProcessPlotter
- linear algebra:
- reversed Cuthill-McKee permutation algorithm, graph in-place permutation
- setting of parameter variables by a user-defined function
- new tests and terms
For more information on this release, see http://sfepy.googlecode.com/svn/web/releases/2009.4_RELEASE_NOTES.txt (full release notes, rather long).
Best regards, Robert Cimrman

Hi Robert, Thanks for the new version. I put it on my 32 bit ubuntu jaunty. All tests ran fine without any errors. Then I tried isfepy.

Hi Osman,
thanks for trying out the new version! As isfepy works for me, I assume it must be a version issue with mayavi (tested with 3.3.0). What is your mayavi version?
If you cannot try 3.3.0, or use it already, could you send me the output of 'gui.scene.print_traits()'? Just put it prior to the offending line...
cheers, r.

It is 3.1.0 (mayavi2). I'll try to update , but don't want to break my ubuntu :-)

I see. Well, in fact I do not see right now how to get to the required scene instance.
But I have asked Gael if there is a workaround, in case you cannot upgrade.
Cheers, r.
