examples (wiki)
by Robert Cimrman 01 Apr '10

01 Apr '10

Hi all, The examples at [1] are very old (*) and not very well formatted. Has anyone something nice and interesting to replace them? The site [1] should contain preferably examples from sfepy users (if such a beast really exists), as the work of the team I am in is presented at [2]. I would like to move the old examples to an OldExamples wiki page for the record. r. (*) 14 test file(s) executed in 13.51 s, 0 failure(s) of 18 test(s) - now it's 59 tests [1] http://code.google.com/p/sfepy/wiki/Examples [2] http://sfepy.kme.zcu.cz/

Some help about postproc.py
by Sylvain Arreckx 05 Mar '10

05 Mar '10

Hello, I installed your sfepy software yesterday without any trouble. I'm on ubuntu 9.10 Karmic and I have mayavi2 installed and working properly I followed the installation process. I ran ./runTests.py and got : << directory: tests, test files: 37 37 test file(s) executed in 86.85 s, 0 failure(s) of 50 test(s) So up to now everything is fine. Today, I tried ./simple.py input/poisson.py and then visualized the solution : ./postproc.py simple.vtk and got that : Traceback (most recent call last): File "./postproc.py", line 288, in <module> main() File "./postproc.py", line 281, in main view = view_file(filenames, filter_names, options) File "./postproc.py", line 147, in view_file step=options.step, anti_aliasing=options.anti_aliasing) File "/home/syarra/Programmes/sfepy/sfepy-release-2009.4/sfepy/ postprocess/viewer.py", line 557, in call_mlab scene = gui.scene.mayavi_scene AttributeError: 'MlabSceneModel' object has no attribute 'mayavi_scene' Could you please help me to solve this problem Thanks Sylvain

pdf version of the docs
by Robert Cimrman 26 Feb '10

26 Feb '10

Hi, thanks to Logan's effort, there is now a PDF version of the docs, see [1]. The term table is still a bit bloated though. To fix that, we can either shorten some very long class names and the formal term argument names, and/or include less information into the PDF version of the table (e.g. just name, link and definition). Is there a way in sphinx for selective docs generation based on the target format (html vs. latex vs....)? r. [1] http://docs.sfepy.org/doc-devel/

overview of terms in sphinx docs
by Robert Cimrman 22 Feb '10

22 Feb '10

Hi, I have added a basic autogenerated table of all available terms to the sphinx docs, see [1]. The sphinx docs now contain everything that was in the good old sfepy_manual.pdf (except the tables of notation - any volunteer for an easy job?), so I am going to remove the old documentation stuff soon. It would be good to release 2010.1 this month, so try the git version and report bugs, please, if you can find some spare time. r. [1] http://rc.github.com/sfepy/term_table.html

basic term documentation
by Robert Cimrman 01 Feb '10

01 Feb '10

Hi, At [1] you can see the basic sphinx documentation of the terms (scroll down). It took me some time to convert the docstrings, but the result is not bad. The new sources are for the moment at [2], I will push it to the master repo after I get some feedback. I do not know yet how to hide the common methods of the terms, i.e. do the following split: 1. The Term class documentation with all the common methods 2. The Term subclass documentation with only Description, Definition, and possibly the extra methods not already defined by Term. After this is done, we could happily abandon the old way of generating the sfepy_manual.pdf (which is broken now anyway, as the docstrings changed). r.
