OOFEM - free object oriented finite element code

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 1.8; released March, 3, 2008

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.

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.

Official Release of OOFEM, version 1.7

The official release of OOFEM 1.7 is now available.

Added new solution algorithm for incompressible flow with SUPG/PSPG stabilization.
Added support for incompressible analysis of two immiscible fluids (including free surface flows) on a fixed domain in 2D, based on VOF approach.
Added new Direct Sparse Solver (contributed by R. Vondracek). Use --enable-dss when running configure.

For more information see the ChangeLog.

Official Release of OOFEM, version 1.6

The official release of OOFEM 1.6 is now available. A quick summary of the new features in this version:

Adaptive framework released. This includes new classes representing general error estimator, remeshing criteria and mesh generator interface. The adaptive linear and nonlinear static analyses are now available. True adaptivity with primary and internal variables transfer is supported.
Added new FM module (Fluid dynamic). It now includes CBS algorithm for incompressible transient flow analysis, constitutive model for Newtonian fluid, and linear 2d element with equal order velocity and pressure interpolation.
Implementation of MDM model (Anisotropic damage model).
Introduced new keywords in domain components size record! This includes ndofman, nelem, nmat, ncrosssect, nbc, nltf to identify number of domain components. See Input Manual for details.
