I am pleased to announce the release of SfePy 2009.2.

SfePy (simple finite elements in Python) is a software, distributed 
under the BSD license, for solving systems of coupled partial 
differential equations by the finite element method. The code is based 
on NumPy and SciPy packages.

Mailing lists, issue tracking, git repository: http://sfepy.org
Home page: http://sfepy.kme.zcu.cz

People who contributed to this release: Vladimir Lukes.

Major improvements:
- new scripts:
   - isfepy (interactive sfepy) - customized IPython shell for quick 
"compute and visualize" work
   - postproc.py - a script to visualize (via mayavi2) results saved in 
result files
   - probe.py - a script to probe and plot results along geometrical 
objects (e.g. lines, rays) intersecting the mesh
- automatic html documentation generation via doxygen
- extended syntax of equations to allow boundary traces of variables
- fixed live plotting via multiprocessing for multi-core machines
- short input syntax for LCBC conditions, fields, integrals, materials 
and solvers
- new solvers:
    - Broyden and Anderson nonlinear solvers (SciPy implementation)
- new mesh readers:
   - Nastran (.bdf) format
   - Abaqus ascii (.inp)
- new example problems, tests and terms

Applications:
- phononic materials:
   - plotting improved
   - caching of eigen-problem solution and Christoffel acoustic tensor
- schroedinger.py:
   - choose and call DFT solver via solver interface
