OpenFEM is a set of finite element tools that manages multiple (multi-physical) phenomena designed to be used within a matrix computing environment, such as matlab or scilab. The currently available version has been developed between the MACS team of INRIA and the SDTools company from the MODULEF and SDT (Structural Dynamics Toolbox) libraries. OpenFEM is distributed under the GNU-LGPL license. Among the next developments, the inclusion of OpenMP directives for the best use of parallel architectures is contemplated.

Mode of use
To perform a calculation with OpenFEM, the following steps are performed:


 * Definition of the geometry on which the problem is defined. Definition of the elements of the mesh that represents the problem, based on the given geometry. Definition of the properties of the materials used.  Definition of the properties of the elements.  Definition of the problem model, generally using the OpenFEM femesh tool or importing it from an external modeling tool.  Definition of edge conditions  Definition of charges  Resolution of the problem, for which OpenFEM provides resolution tools for static responses to load cases. Non-linear resolution tools are under development (2005). For dynamics problems, eigenvalue (Lanczos) and transit (Implicit and explicit Newmark, Galerkin discontinuous in time, linear and non-linear) resolution tools are available.
 * Once the computations have been made, the scilab version has tools for visualizing results. These include, visualization of the mesh, animation of the deformations and coloring based on a stress vector. An interface with the Medit visualization and animation tool is also included.
