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?

Progress Bar
by Md. Golam Rashed
As analysis takes quite some time, it'll be helpful if there is a progress
bar or progressing % showing.
example:
progress 1%
progress 2%
progress 3%
.
.
.
.
.
.
progress 15%
.
.
etc.
this feature will really help large problem.
is it possible to integrate this feature into sfepy???
Thanks

Re: sfepy possibilities
by Robert Cimrman
IMHO no, SfePy does no have discrete structure elements like trusses. It might be possible to extend, as other components (solvers, assembling, ...) are available, but I do not know complexity of the task, as I do not know fram3dd.

Could one achive a similar result with sfepy to frame3dd (http://
frame3dd.sourceforge.net/) for structural analysis of frames? I know
the input is different a mesh file (but it can be 2d also i think) -
what kind of output does sfepy create and how hard would it be to get
the nodes displacements and forces from that output?

Re: some fixes for sfepy in windows
by Robert Cimrman
Yes, all tests run by runTests.py pass, but there is also test_install.py script that checks some more functionality. I was talking about that.

when sfepy-2011.3 came out, i tried it and there was no error running it on win 7, only 3 warnings. so which errors are you talking about?

some fixes for sfepy in windows
by Robert Cimrman
Hi,
I have fixed test_install.py and mayavi imports for windows, so now I have all
tests ok, and only one failure of test_install.py (due to missing pysparse) on
windows 7!
I followed the guide [1] - it worked without problems, I have just one question:
- step 4. requires msysGit-fullinstall-*, but IMHO Git-* (of msysgit) would be
easier, as it is better integrated with windows environment and contains
gitbash (desktop shortcut possible...), which is a really nice shell behaving
just like in linux. One then does not need to start "msys" by typing the full
path etc.
cheers,
r.

Re: Progress Bar

Yes! Provided the terms used in the weak form of a PDE are already implemented in sfepy. If not, one needs to add them, which may be non-trivial.

OK, so i think anyone with python knowledge can do 3D Finite Element Analysis in sfepy provided that they have the weak formulation of the governing PDE of physical problem and boundary conditions??

Re: Progress Bar

Yes, FEM is a variant of Galerkin method with a special choice of the base - it contains functions with small compact support (tied with the mesh elements) leading to a sparse matrix problem.

Learning FEM
by Md. Golam Rashed
Hi all,
as you can see, i'm bit new to FEM.
and the documentation of sfepy really lacks in theory of FEM implemented in
sfepy.
So, can you people point me out good sources or textbooks which can help me
understanding the detailed working procedure of sfepy??
Thanks!
