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? r. ----- Reply message ----- From: "Andre Smit" <freev...(a)gmail.com> To: <sfepy...(a)googlegroups.com> Subject: Torque Date: Sat, Dec 18, 2010 05:10 What is the best way to apply a torque load to a model? -- Andre -- You received this message because you are subscribed to the Google Groups "sfepy-devel" group.

Progress Bar
by Md. Golam Rashed Jan. 2, 2012

Jan. 2, 2012

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

simple and easy installation of SfePy onto Windows

Oct. 28, 2011

A new wiki page has been created to focus on simple and easy installation of SfePy onto Windows using only python(x,y) as using EPD results in many failures. http://code.google.com/p/sfepy/wiki/Simple_Windows_Installation ** detailed and advanced instructions of windows installation is at http://code.google.com/p/sfepy/wiki/PythonXYWindowsInstall

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. r. ----- Reply message ----- From: "Madis" <madi...(a)gmail.com> To: "sfepy-devel" <sfepy...(a)googlegroups.com> Subject: sfepy possibilities Date: Thu, Aug 25, 2011 01:27 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? -- You received this message because you are subscribed to the Google Groups "sfepy-devel" group.

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. r. ----- Reply message ----- From: "Md.

some fixes for sfepy in windows
by Robert Cimrman Aug. 24, 2011

Aug. 24, 2011

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. [1] http://code.google.com/p/sfepy/wiki/Simple_Windows_Installation

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. r. ----- Reply message ----- From: "Md.

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. r. ----- Reply message ----- From: "Md.

Learning FEM
by Md. Golam Rashed Aug. 17, 2011

Aug. 17, 2011

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!
