I want to write a paper themed on, doing simulation using scripting language with legacy code. As a civil engineer (structural), i find the tensile strength of concrete test presented in sfepy primer quite suitable to use in my writing. will this cause any copyright problem??? And secondly, can anybody detail the process of wrapping python around C in sfepy?? just to make sure my understanding is right. Thanks!

Unless Andre (the primary author of the primer) says differently, our documentation is, like the code, licensed under BSD license, so use what you need. Citing the docs would be nice, of course.

Recently we changed from swig to cython, so the situation is as follows:
The C code is in 'extmods' (as extension modules) subdirectories: sfepy/fem/extmods/ sfepy/physics/extmods/ sfepy/linalg/extmods/ sfepy/terms/extmods/
The Cython wrappers are there as well in .pyx (+ sometimes .pxd) files. Some extension modules are pure Cython (they do not use hand-written C), e.g. sfepy/fem/extmods/assemble.pyx
The Cython code uses numpy arrays as memory buffers. It (usually) works as follows:
- in Python, all input arrays are prepared and output arrays pre-allocated (using zeros() or empty()).
- the C/Cython function is called, filling the output arrays
This approach simplifies very much needs for manual memory management in C. Another simplification is that the C code requires the arrays to be C-contiguous.
If you want to know more, first check the cython documentation, especially the tutorials [1] and the chapter on interaction with numpy [2]. Then also look at the code in the directories mentioned above (disclaimer: I am cython newbie - any comments how to improve the wrappers are welcome!)
Also feel free to ask here, of course.
Cheers, r.

No problem here - the primer falls under the SfePy license.
The test as modeled is per specification : ASTM D6931-07, although there is a concrete equivalent - usually applied to thicker specimen I believe. Someone mentioned to me that the test was originally developed to test concrete - it was known as the Brazilian test.

To wrap python around fortran I use F2py <http://www.scipy.org/F2py>, which is maintained as part of numpy. This has allowed me to compile legacy codes like BISAR and ELSYM5 for use within python.

What Latex editor do you people use to write for journal? it feels quite difficult for me to write in any tex software, is there any easy what-you-see-is-what-you-get available??
Note: I'm an MS office word user, and i'm fine as long as a journal excepts in doc/docx format. but trouble begins when latex is mandatory.
Lyx is pretty good.

so i heard and tried once, but its too much resource hungry! Thanks 4 the feedback. anyone wanna add something in this regard?

How about Texmacs? Maybe even more resource hungry but nice :-)

I am using emacs, which is very good, but not for everone :)
BTW. after writing in LaTeX for a while IMHO you will not need a wysiwyg editor. What is more important is good syntax highlighting, insertion of LaTeX symbols and evnironments, word completion etc. After all, it is about document contents and structure, not its rendering while you type.
On windows, WinEdt (shareware) or LEd (freeware) are pretty good.

What about Sphinx? is it good for latex?
It is perfectly ok for simple latex, but as each journal supporting latex submissions has its own (latex) style, it might be better to write in latex directly using that style.

Hi all,
I wrote a journal article to The " International Journal of Computer Applications" and it got published as the editors choice of Issue 14 of Volume 40. It was themed on doing simulation using scripting language with legacy code.

Thanks Andre for the permission!
Now, what is the feeling of you guys about the paper?

Andre smit,
I've emailed you on freevryheid[at]gmail[dot]com about a potential paper writing. did u get it?
