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

Dear experts,
I installed sfepy in lubuntu15.04.
I tried ./run_tests.py --debug and encounterd the error as attached file.
Could you tell me what to do for this error?
Best regards,

Dear All,
does SteFy handle non-orthogonal meshes? I mean, does it include the
non-orthogonal correction and skewness correction?
Thanks in advance,

Dear Experts,
Now I have a question,I am trying to find the tetrahedra according the
vertices in the face in a .mesh file.
For examples,in the file,I know the vertices on right boundry, and I want
to find the tetrahedra, it consists 4 vertices.
How can I solve it?

Dear Experts,
My nickname is pyontaku14.
I tried run_tests.py with Python2.7.8 on Windows8.1.
The result of "python run_tests.py --filter-less" is the
attached 150621_sfepy_test_filter.txt.
The result of "python run_tests.py --debug" is the
attached 150621_sfepy_test_debug.txt.
"AttributeError: SetSource" is in 50621_sfepy_test_debug.txt.
I could not understand what this error is.
I guess all required modules are installed.
Could you please tell me what to do?
Any help is welcome.
Best regards,
After normal inplace build process (ubuntu 12.04 64bit, Anaconda+python
2.7.9) I run testing and got one failure in module test_mesh_smoothing.py
Here is the output of the command:

I checked the file sfepy/linalg/utils.py and found out that numpy 1.9.2

lapack_lite really has no dgetrf (older version do have) attribute. It
seems to me easy to fix but maybe I am too naive. Any suggestions?
Hi,
I have the Enthought Canopy Python distribution and am new to using SfePy.
I was trying to work through the examples and had a problem with viewing
the results. The package manager in Canopy already has SfePy Version 2014.4
Build 6. Whenever I try to use the Viewer to look at results, I get:
ERROR:mayavi.core.common:Exception
Traceback (most recent call last):

I have no idea what the problem is. It happens on my Mac (running Yosemite)
and also my Windows 7 machine.
I would greatly appreciate any help with this.
Thanks.

Hi
I'm using SfePy to solve a problem.Firstly, I creat a simple cube by Gmsh
and save as my.mesh file.
Now I am using sfepy/examples/multi_physics/biot.py to calculate.but it
something wrong.
Then I open the "/meshes/3d/cube_medium_hexa.mesh",in the
"cube_medium_hexa.mesh" file,it consists Vertices and Hexahedra.But in my
mesh file,it only consists Vertices,Edges and Triangles,no Hexahedra. When
I run the biot.py, there aren't any results I want. How can I save .mesh
file including Hexahedra? I think it is the main probelm.
Regards,
Kid
