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?

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

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

Anaconda Install Instructions
by Daniel DeSantis
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

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

Material Model and a solver implementation in SfePy
by Madhu Mahadevappa
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.
