OpenFEM is an open-source software freely distributed under the terms of the ”GNU Lesser Public License” (LGPL) co-owned by INRIA and SDTools. OpenFEM is a general purpose multi-physic FEM environment. It addresses people familiar with FEM who want state of the art performance with the ease of use of MATLAB. Easier learning and more user friendly access is provided by SDTools in the OpenFEM version integrated in SDT. OpenFEM by itself is thus mostly used by academics who are willing to develop in a non graphical mode. SDTools is the main contributor to OpenFEM but has collaborations with a number of other developers, who need to rely on an Open Source environment.
