Welcome on OOFEM official page
OOFEM is free finite element code with object oriented architecture for solving mechanical, transport and fluid mechanics problems that operates on various platforms.
The aim of this project is to develop efficient and robust tool for FEM computations as well as to provide modular and extensible environment for future development. OOFEM is released under GNU General Public License (GPL).
The current version of OOFEM is 2.1; released Dec, 22, 2011
The following is a list of recent additions to this web. Whenever a new paper or specification is written or important event happens, a notice will be put here. The most recent changes are listed first.

- Implemented new SlipWithFriction, PenetrationWithResistance, OutFlowBC, and isotropic surface tension boundary conditions for flow models.
- Added LAPACK-bindings for FloatMatrix class, updated to PETSc 3.2, optimization of PETSc interface.
- And many improvements and bug-fixes, for more information see the ChangeLog

Announcing trac@oofem
Every application has bugs -- as long as humans write code. Every project needs the participation of its users to identify bugs, as well as to plan for new features.
We are happy to announce the availability of the bug tracking system, based on Trac project. All types of feedback — whether they're genuine bugs or feature requests — are to be reported using trac ticket system.
The oofem bugtracker is available at https://www.oofem.org/trac.

unv2oofem tool released
The new unv2oofem convertor translates unv-mesh (SRDC's I-DEAS) file format to native OOFEM input file. Unv file-type is an open ASCII datafile, which is used by several finite element codes. For example, this tool allows to use open-source SALOME pre-processor to prepare oofem model.
For more details, see description of Unv2oofem at oofem wiki.

Official Release of OOFEM, version 2.0
The development team is pleased to announce the official release of OOFEM 2.0. New features include:- New library for elastic homogenization now includes elastic homogenization schemes, such as Mori-Tanaka or self-consistent ones.
- Many new material models: model for cement hydration, based on CEMHYD3D model, damage-plastic model for concrete concreteDPM, hyperelastic material (for large strain), anisotropic plastic-damage model (for trabecular bone), isotropic elastoplastic material with Mises yield condition (large-strain plasticity). Many enhancements of existing models.
- Added Isogeometric analysis module. New inpterpolation classes for B-splines, NURBS, and T-spline surfaces and solids. New plane stress and 3d IGA elements for structural analysis.
- And many improvements and bug-fixes, for more information see the ChangeLog

Project Wiki launched!
- Launched project wiki, aimed to promote collaboration between OOFEM users and to provide a knowledge base that can be used and extended by its users. Have a look on it, use it, and contribute to it!
2/3/2007
New Forum and SVN access available!
- I'm pleased to announce the availability of anonymous, read-only, public access to the OOFEM Subversion repositories. That way you can pick up any version (including releases) of OOFEM that is in our repository or our web pages and it also allows you to get the actual development version. Read more here.
- New forum has been created with several categories. Registering on forum gets you access to post new messages, get support, and much more. The forum is available at www.oofem.org/forum.
