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

Dear Robert
I could overcome my previous problems of not having root privileges, so it
all worked up till the command:
./postproc.py cylinder.vtk
This echoed the below message:

I'm using Python 2.7.8 if that's relevant to the current issue.
Thanks again

Hello,
I'm trying to install SfePy on a 64-bit windows XP machine with anaconda.
I'm afraid I'm not quite following the instructions. I have anaconda and
tried following the directions for Windows though I saw that is for
python(x,y). I keep running into errors. Is there an updated set of
instructions somewhere?
Thanks for the help
Dan
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,
I want to implement a constitutive model for ice in compression which is
developed using damage mechanics. Damage mechanics in the model utilizes
Schapery's approach, which in turn derived from non-linear viscoelastic
theory.I also want to implement an explicit solver which can capture
high-speed dynamic events accurately.Could you help me understand what it
will take to implement this material model, what SfePy can already do, and
what I will need to contribute to for making this project work?
This project is being carried out to know how easy is to use SfePy for the
research that is going on in our university and to contribute for open
source softwares like SfePy. The results will also be validated by
comparing with the experimental.
Please refer the attached paper for further details about the material
model.
