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?

Hi,
I have just updated the time stepping solvers in sfepy for interactive use, as
demonstrated in the new example [1]. For basic use, ignore the probing code -
the time stepper can be used as simply as:
tss = SimpleTimeSteppingSolver({'t0' : 0.0, 't1' : 100.0, 'n_step' : 11},
problem=problem)
tss.init_time()
for step, time, state in tss():
pass

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

I have made an inline instalation of sfepy-2013.3 on fedora22 , I run the
tests and I have only 3 failed, they maybe related to the parallel option
since I don't have instaled that option. I have python 2.7.10, mayavi
4.4.3, VTK 6.1.0, Qt 4.8.6
Either on the python or ipython window when I try to import:
*from sfepy.postprocess.viewer import Viewe*r
I get the following message,
*cannot set toolkit to wx because it has already been set to qt4*
and of course any postprocessing will fail
Dear Robert,
I would like to the model the viscoelastic behavior of active fibers, as
you done in the paper: "Modelling heart tissue using a composite muscle
model with blood perfusion" or as here:
http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.488.5795&rep=rep1&… and
I was wondering if is easy to implemented in sfepy and/or if there is some
predefined term in Sfepy, since for example the term "dw_tl_fib_a" doesn't
include the "exp{k min(0;de/dt}}" that appears in the paper.
Thank you very much for your help :)
I have installed sfepy 2015.3 on python 2.7.10, mayavi 4.4.3, VTK 6.1.0 and
Qt 4.8.6
All but three tests not related to viewer have passed.
On the python or ipython windows when I try to import:
from sfepy.postprocess.viewer import Viewer
I get the following message:
/usr/lib/python2.7/site-packages/traits/etsconfig/etsconfig.pyc in _set_too
lkit(self, toolkit)
211 if self._toolkit and self._toolkit != toolkit:
212 raise ValueError, "cannot set toolkit to %s because it
has "\
--> 213 "already been set to %s" % (toolkit, se
lf._toolkit)
214
215 self._toolkit = toolkit
ValueError: cannot set toolkit to wx because it has already been set to qt4
can somebody help with this problem?. I am new with sfepy.
Hello everyone,
I desire to implement my own finite element, where I made a semi-analytical
integration. Using symbolic computation symbolic expressions were found to
determine the components of the stiffness matrix. This analytical
integration is much more efficient at run time compared with calculations
by numerical integration.
However, I have been looking for ways to edit the way to calculate the
stiffness matrix is made and find nothing. That is, I do not find how to
edit the way that this matrix is evaluated.
Immensely grateful if someone could guide me to edit files. Or at least see
if I can or can not do that edition.
Thanks in advance.
