... simple finite elements in Python
Note: recent documentation and examples can be found at http://sfepy.org. This site serves for issue/bug tracking, downloads, mailing lists and wiki, which can be used for temporary documents or to prepare documents later to be included in the main sphinx documentation.
News- 05.12.2011 Version 2011.4 released (cython used instead of swig to interface C code, many terms unified thanks to new optional material term argument type, updated Lagrangian formulation for large deformations, automatic generation of gallery of examples, etc.), see 2011.4_RELEASE_NOTES.txt
- 10.08.2011 Version 2011.3 released (major update of terms aiming at easier usage and definition while retaining original C functions, overriding problem description items on command line, improved developer guide, Primer tutorial - a step-by-step walk-through of the process to solve a simple mechanics problem, etc.), see 2011.3_RELEASE_NOTES.txt
- 31.05.2011 Version 2011.2 released (experimental implementation of terms aiming at easier usage and definition of new terms, Mooney-Rivlin membrane term, update build system to use exclusively setup.py, allow switching boundary conditions on/off depending on time, support for variable time step solvers, etc.), see 2011.2_RELEASE_NOTES.txt
- 24.03.2011 Version 2011.1 released (discontinuous approximations, user-defined material nonlinearities, improved surface approximations, speed-up mesh reading, extensive clean-up - less code, many bugfixes and many more updates), see 2011.1_RELEASE_NOTES.txt
- 06.12.2010 Version 2010.4 released (higher order elements, refactoring of geometries (reference mappings), transparent DOF vector synchronization with variables, interface variables defined on a surface region, many bugfixes and many more updates), see 2010.4_RELEASE_NOTES.txt

Key Features- solving many problems described by PDEs:
- linear problems: linear elasticity, Poisson equation, Stokes, Darcy flow, Biot problem
- nonlinear problems:
- Navier-Stokes equations
- finite deformations: hyperelastic neo-Hookean, Mooney-Rivlin materials in the total Lagrangian formulation
- other PDEs containing the implemented terms, both 2D and 3D
- problems in complex domain (e.g. acoustics)
- fading memory terms
- particular applications (see http://sfepy.org)
- acoustic band gaps in phononic materials (similar to forbidden frequency ranges in photonic crystals, see http://en.wikipedia.org/wiki/Photonic_crystal)
- Schroedinger equation
- homogenization of porous media (modelling of muscle tissue, bones, engineering porous materials)
