Re: Torque
by Robert Cimrman
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?

1D line elements in SfePy
by Nimish
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

repo rewrite
by Robert Cimrman
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.

Grabbing the mass matrix
by Sukhbinder Singh
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

Macport safety run_tests.py bug
by davidamb...＠gmail.com
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.
