ok, i got it. it'd be very much helpful to have one. however, i'm seeking theory behind sfepy. can you help me in this regard? thanks.
Well, the theory is well described in any finite element textbook, and even on-line (e.g. the site Vladimir mentioned) - it's one of standard methods to solve PDEs (partial differential equations). SfePy implements the basic version without mesh adaptivity, and uses, for the moment, the most classical, Lagrangian, basis for polynomial approximation on elements.
If you are really interested in the actual implementation, currently the best way is to look at the source code in sfepy/fem, starting with sfepy/fem/problemDef.py where the ProblemDefinition class is defined. But before that, go through the tutorial (check especially "Sneak peek: what is going on under the hood" and "Interactive Example: Linear Elasticity" sections).
There is no real "user" documentation of sfepy.fem yet. It would be nice to have, but I do not have currently power to do it. But I can try to answer any particular question, so if you have any, ask... :)
