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
Nimish
FYI: As SciPy 0.12.0 is out and one of the release highlights is "Support for
Python 2 and Python 3 from the same code base (no more 2to3)", we can think
seriously about updating SfePy in this respect as well, cf. [1].

Dear SfePy users,
Is it possible to evaluate a solution not only in the FEM mesh node, but in
any arbitrary point in the domain with the given (x, y, z) coordinates?
For example, consider Dirichlet problem for Poisson equation. We apply
essential boundary conditions on the surface nodes and after the problem
has been solved we have the solution vector, i.e. vector of values in the
FEM mesh nodes. But I want to know the solution in point v(x, y, z) that is
not FEM mesh node. What is the best way to obtain solution in this point v?
Sincerely,
Alec Kalinin
I am pleased to announce release 2014.1 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.

Highlights of this release
--------------------------
- sfepy.fem was split to separate FEM-specific and general modules
- lower memory usage by creating active DOF connectivities directly from field
connectivities
- new handling of field and variable shapes
- clean up: many obsolete modules were removed, all module names follow naming
conventions
For full release notes see http://docs.sfepy.org/doc/release_notes.html#id1
(rather long and technical).

Hi,
several important changes for users of "SfePy as a library to build apps" will
be in the next release of SfePy (to be soon) and are already in the master
repository. Those are:
1. sfepy.fem has been reorganized and split into code that is discretization
method independent (now in sfepy.discrete and sfepy.discrete.common) and FEM
specific (now in sfepy.discrete.fem).
2. all source files in the repository now use the same naming conventions (no
more thisStyle.py modules, only this_style.py).
3. isfepy was removed, see the docs for an advice how to setup ipython for the
same functionality.
4. a number of unused/underused modules were removed.
If you have any feedback, do not hesitate to post.
Regards,
r.
FYI: I am going to remove the isfepy ipython-based shell from sfepy, as it has
not much value over plain ipython. An information will be added to the docs
saying what to put into an ipython startup file to get the same functionality.

Hi all
I recently cloned the source from github and all the tests passed. I am
trying to run posproc.py on cylinder.vtk and it results in the following
errors.
