ANN: SfePy 2009.1

I am pleased to announce the release of SfePy 2009.1.

SfePy (simple finite elements in Python) is a finite element analysis software based primarily on Numpy and SciPy.

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

Major improvements:

• new solvers:
  • simple backtracking steepest descent optimization solver
  • PETSc Krylov solvers via petsc4py, sequential mode
  • LOBPCG eigenvalue solver (SciPy implementation)
• new mesh readers:
  • mesh3d (hermes3d)
  • AVS UCD ascii mesh
  • Hypermesh ascii mesh
• homogenization framework:
  • unified approach to resolve data dependencies: HomogenizationEngine class
• switched DVCS from mercurial to git

Applications:

• phononic materials:
  • dispersion analysis, phase velocity computation for phononic materials
  • caching of coefficients to speed up parametric runs
• schroedinger.py:
  • fixed DFT iterations, iteration plot saving
  • basic smearing around Fermi limit
