Re: Torque

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.

simple and easy installation of SfePy onto Windows
by tone....＠gmail.com 28 Oct '11

28 Oct '11

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

easier_terms branch merged
by Robert Cimrman 27 Jul '11

27 Jul '11

Hi, I have merged significant changes related to terms into the master repository. It is easier now to add new terms. The merge resulted in: 63 files changed, 2790 insertions(+), 3765 deletions(-) so you can see the code is much shorter now (check, e.g., the BiotTerm before and after the merge), retaining or even improving the original functionality. The test_install.py script reports no errors for me (and the elapsed times should be around 40s (examples) and 80s (tests) on a recent-enough computer, see test_install_times.log created after you run it), however note that not all terms were updated yet for the new term evaluation code, as not all terms are covered by tests (unfortunately). I will update all terms eventually as I will need them, but the time frame is vague, so let me know about any problems to increase priority of terms you need :) The 'adding a new term' document needs an update as well, so again, if anyone wishes to add a new term, nag here... cheers, r.

importing mayavi
by freevryheid 27 Jul '11

27 Jul '11

To get isfepy to run I needed to change 3 files to satisfy mayavi installation on archlinux - really just the imports by stripping "enthought" and changing "traits.ui" to "traitsui". My mayavi installation comprises the following community compiled modules: python-enthought-mayavi 4.0.0-1 python-enthought-utils 4.0.0-1 Not sure if these issues are also in the mayavi git version. Anyway - here's the three files that change: 1. /sfepy/sfepy/postprocess/viewer.py """ from enthought.traits.api \ import HasTraits, Instance, Button, Int, Bool, on_trait_change from enthought.traits.ui.api \ import View, Item, Group, HGroup, spring from enthought.traits.ui.editors.range_editor import RangeEditor from enthought.tvtk.pyface.scene_editor import SceneEditor from enthought.mayavi.tools.mlab_scene_model import MlabSceneModel from enthought.mayavi.core.ui.mayavi_scene import MayaviScene """ from traits.api \ import HasTraits, Instance, Button, Int, Bool, on_trait_change from traitsui.api \ import View, Item, Group, HGroup, spring from traitsui.editors.range_editor import RangeEditor from tvtk.pyface.scene_editor import SceneEditor from mayavi.tools.mlab_scene_model import MlabSceneModel from mayavi.core.ui.mayavi_scene import MayaviScene 2. /sfepy/sfepy/postprocess/dataset_manager.py """ from enthought.traits.api import (HasTraits, Instance, Array, Str, Property, Dict) from enthought.tvtk.api import tvtk from enthought.tvtk.array_handler import array2vtk """ from traits.api import (HasTraits, Instance, Array, Str, Property, Dict) from tvtk.api import tvtk from tvtk.array_handler import array2vtk 3. /sfepy/sfepy/postprocess/sources.py """ from enthought.tvtk.api import tvtk from enthought.mayavi.sources.vtk_data_source import VTKDataSource from enthought.pyface.timer.api import Timer """ from tvtk.api import tvtk from mayavi.sources.vtk_data_source import VTKDataSource from pyface.timer.api import Timer
