In examples/large_deformation/hyperelastic.py a rotation by displacements is applied. By using a similar function the vectors defining the force couples could be defined for dw_surface_ltr (IMHO). Does it make sense?

What is the best way to apply a torque load to a model?

I am currrently looking for FEM packages to help me solve a system of
beams and columns, basically a collection of 1D bernoulli/timoshenko
line elements.
I started reading SfePy docs and i am getting the idea that doing the
above is not really possible here, am i right?
Are only 2D area elements permitted in SfePy?
Or is there any direct support for solving 1D line elements too..
Cheers

Dear Robert Cimrman,
I am trying to implement elastic inclusion problem. It is a 2D mesh with
an inclusion(and therefore eigenstrain) at mesh centre. I developed my
codes(as attached) based on following two previous issues.
https://groups.google.com/forum/#!searchin/sfepy-devel/Ronghai/sfepy-devel/…https://groups.google.com/forum/#!searchin/sfepy-devel/elastic$20periodic$2…
But I have troubles with the boundary conditions. I would like to try two
kinds of boundary conditions:
(1) Top and bottom boundaries: uniaxial loading(or surface traction). Left
and Right boundaries: periodic. I used "dw_tl_surface_traction" but some
errors come out.
(2) Periodic at all boundaries. I think there must be a easy way for this,
but failed to find out in SfePy documentation and mailing list.
Could you please give me some help. Thanks.
Regards
Ronghai
I am pleased to announce release 2015.1 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 or by the
isogeometric analysis (preliminary support). It is distributed under the new
BSD license.
Home page: http://sfepy.org
Mailing list: http://groups.google.com/group/sfepy-devel
Git (source) repository, issue tracker, wiki: http://github.com/sfepy
Highlights of this release
--------------------------
- support for multiple fields in isogeometric analysis
- redesigned handling of solver parameters
- new modal analysis example
For full release notes see http://docs.sfepy.org/doc/release_notes.html#id1
(rather long and technical).
Best regards,

Hi all,
I screwed up some commits in the near past so now I have used the git weapon of
mass destruction a.k.a. GFB. The history is changed, so, please, do not pull to
your repositories! Use a fresh clone, or fetch, instead.
Sorry for the inconvenience.

Hi this might be a silly question, but am not able to find a way to get the mass matrix from the problem in sfepy.
I can get the stiffness matrix K but how to get the Mass matrix M.
Any help is appreciated. Thanks
Using sfepy with python 2.7, MacPorts installation on Yosemite.
Tried to run
python run_tests.py
but most tests failed.
ran in debug mode and found that there was a problem finding certain
dependent files:
IOError: [Errno 2] No such file or directory:
'/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/meshes/elements/2_3_2.mesh'
Had a look at the directory structure and I think the correct directory it
should have is:
'/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/
sfepy/meshes/elements/2_3_2.mesh'
When I modified one test case (test_cmesh.py) accordingly this seemed to
solve the issue. Hope this is helpful.
Dave
