Hey guys
First off let me congratulate you on an excellent FEM application. The
more I get into it, the more I appreciate the volume of work that has
gone into it :) I particularly like the way a problem is defined using
python. I've never come across anything else that allows such a simple
yet powerful definition. I understand that the app is still under
development and that the documentation is lacking. My experience with
FEM software has mostly been "blackboxed" using ABAQUS, etc. My lack
…
[View More]of knowledge on the (weak) formulation of a problem is severely
restricting my application of SfePy. For example, I have not been able
to figure out how to output stresses and strains in the model using
linear elastic analysis - the example provided only outputs
displacements. Can someone please point me in the right direction.
Regards
Andre Smit

Hi all,
The examples at [1] are very old (*) and not very well formatted. Has anyone
something nice and interesting to replace them? The site [1] should contain
preferably examples from sfepy users (if such a beast really exists), as the
work of the team I am in is presented at [2].
I would like to move the old examples to an OldExamples wiki page for the record.

Hi all,
the version 2010.1, when installed system-wide, has wrong paths to meshes
and other data files. It is still usable, but the tests fail so if you do
not want to use sfepy in-place and you want all tests ok, get the latest
git snapshot at [1].

Hello,
I installed your sfepy software yesterday without any trouble.
I'm on ubuntu 9.10 Karmic and I have mayavi2 installed and working
properly
I followed the installation process.
I ran ./runTests.py and got :
<< directory: tests, test files: 37
37 test file(s) executed in 86.85 s, 0 failure(s) of 50 test(s)
So up to now everything is fine.
Today, I tried ./simple.py input/poisson.py
and then visualized the solution : ./postproc.py simple.vtk
and got that :
Traceback (most recent …

File "./postproc.py", line 288, in <module>

Could you please help me to solve this problem
Thanks

I am pleased to announce release 2010.1 of SfePy.
Description
-----------
SfePy (simple finite elements in Python) is a software for solving systems of
coupled partial differential equations by the finite element method. The code
is based on NumPy and SciPy packages. It is distributed under the new BSD license.
Mailing lists, issue tracking, git repository: http://sfepy.org
Home page: http://sfepy.kme.zcu.cz
Documentation: http://docs.sfepy.org/doc
Contributors to this release: Vladimí…
[View More]r Lukeš, Logan Sorenson.
Highlights of this release
--------------------------
- new sphinx-based documentation
- refactoring of base functions (polynomial spaces) and element geometry
description
- interpolation between different meshes
- terms for describing perfusion and active fibres in the total Lagrangian
formulation (applicable, for example, to active muscle tissue models)
Major improvements
------------------
Apart from many bug-fixes, let us mention:
- data probing:
- automatic refinement of probe points, speed-up
- postprocessing and visualization:
- VTK source construction for any format supported by MeshIO classes:
- this means displaying meshes in formats Mayavi knows nothing about
- graphical logging:
- support logging to a text file, vertical line plot, allow several Log
instances
- new examples:
- application of the theory of homogenization to elasticity
- perfusion, active fibres
- new tests and many new terms
