= Calculix =

A package designed to solve field problems. The method used is the finite element method. With CalculiX Finite Element Models can be build, calculated and post-processed. The pre- and post-processor is an interactive 3D-tool using the openGL API. The solver is able to do linear and non-linear calculations. Static, dynamic and thermal solutions are available. Both programs can be used independently. Because the solver makes use of the abaqus input format it is possible to use commercial pre-processors as well. In turn the pre-processor is able to write mesh related data for nastran, abaqus, ansys, code-aster and for the free-cfd codes duns, ISAAC and OpenFOAM. A vda CAD interface is available. The program is designed to run on Unix platforms like Linux and Irix computers but also on MS-Windows.

= FEniCS project =

FEniCS project (wikipedia): a set of free software projects with the common goal to enable automated solution of differential equations. It provides software tools for working with computational meshes, finite element variational formulations of PDEs, ODE solvers and linear algebra. FEniCS project home page.

= FreeFEM++ =

FreeFEM++: is an implementation of a language dedicated to the finite element method, written in C++, with the FreeFem++ language being a C++ idiom. Problems involving PDE (2d, 3d) from several branches of physics such as fluid-structure interactions require interpolations of data on several meshes and their manipulation within one program. FreeFem++ includes a fast 2^d-tree-based interpolation algorithm and a language for the manipulation of data on multiple meshes.

= Elmer =

Elmer is an "Open Source Finite Element Software for Multiphysical Problems". A recent (as of 6 May 2011) discussion on the users group mailing list of Calculix (see also section Calculix here) indicated that there is a problem with the documentation of Elmer:
