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 Lesser General Public License (LGPL).
The current version of OOFEM is 2.5 released Dec, 30, 2017
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.
OOFEM releases citable
starting from today OOFEM releases are archived on Zenodo and have DOI, so they are directly citable.
