Re: Torque
by Robert Cimrman 09 Mar '18

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 02 Jan '12

02 Jan '12

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

going cython

FYI: conversion to cython is in progress, see [1]. So far so good, but if any cython expert is around and has a spare minute, I would appreciate a feedback. r. [1] https://github.com/rc/sfepy/tree/cython

simple and easy installation of SfePy onto Windows

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

gallery
by Robert Cimrman 09 Sep '11

09 Sep '11

The initial version of the gallery is online [1]. I guess we should use a bit more different meshes in the examples, as now the page looks quite boring. :) r. [1] http://docs.sfepy.org/gallery/gallery.html

generated pages of examples
by Robert Cimrman 07 Sep '11

07 Sep '11

Hi, I have started working on a script for generating something like the famous matplotlib gallery for sfepy examples. The examples page [1] is already usable, although there are some issues to solve, to name a few: - failed examples produce no images, but there is still the link - some directories need to be skipped - latex version of the docs fails compiling without errors - example docstrings are not included yet (need to add them to all examples first!) Usage of the script on linux for those willing to try it: ./script/gen_gallery.py cp -ra gallery/examples/ doc/ cd doc make html firefox _build/html/index.html Due to some issues with offscreen rendering a window pop-ups when generating the images - set it to "keep below others" if your window manager allows that That's it. Comments, suggestions, improvements etc. welcome! r. [1] http://docs.sfepy.org/doc-devel/examples.html

scipy central
by Robert Cimrman 02 Sep '11

02 Sep '11

FYI: there is now a new site for sharing scipy-related code snippets and for posting links to scipy related packages, see [1]. I was asked by Kevin Dunn, the site author, to add SfePy, but did not get to do it yet -> issue 155 [2].

converting old examples to Sphinx
by Robert Cimrman 02 Sep '11

02 Sep '11

FYI: There is a new EasyToFix issue [1], so if anybody wants to help a bit while improving his/her sphinx-fu, give it a shot. I am talking especially about the ExampleUsingSalomeWithSfePy. The plan is to slowly transition all documents to Sphinx, and put it to sfepy.org. The google site will be used for issues, mailing lists, downloads and wiki (for initial versions of various docs before putting them to the main documentation). r.

Crack propagation
by Torsten Bronger 01 Sep '11

01 Sep '11

Hallöchen! I try to model crack propagation in thin film with sfepy. I must admit that I don't understand everything in the docs because my FEM knowledge is mediocre at best, but my plan is the following: 1. I take the "Linear Elasticity" example as a starting point (2.5.1 in the manual) 2. I substitute my own mesh and regions, and boundary conditions 3. I solve the problem 4. I look at the tensions between the nodes. If they exceed a certain threshold, the respective connection breaks up. I change the mesh accordingly. 5. I repeat 3 to 4 until no connections have to be broken up anymore Is this a sensible approach?
