Finite Element Analysis

These are some open source software options for Finite Element Analysis:

OpenCASCADE

• Open CASCADE Technology is software development platform freely available in open source. It includes components for 3D surface and solid modeling, visualization, data exchange and rapid application development.

z88

• Z88 is a fast, powerful and compact Finite Elements Analysis Program especially designed for PCs running the great LINUX, workstations and large computers with UNIX and PCs with WindowsXP/95. Z88 features 20 finite element types covering plane stress, plate bending, axial symmetric structures and spacial structures up to 20-node Serendipity hexahedrons. Z88 comes with a user-friendly interface, a powerful mesh generator, a DXF-converter, two plot programs and, of course, two powerful solvers. Import of COSMOS files from Pro/ENGINEER and Pro/MECHANICA is supported. The new version Z88 12.0 is GNU-GPL Freeware.

OpenFEM

• OpenFEM is an open-source software freely distributed under the terms of the "GNU Lesser Public License" (LGPL). It is a general purpose multi-physic FEM environment. (at http://www-rocq.inria.fr/OpenFEM/rubrique.php3?id_rubrique=3 looks really good,
  • needs http://www.scilab.org/ Ubuntu, Debian, Fedora, or other good linux distro in ix86 architecture are best bets for getting this going

femML

• The finite element modeling Markup Language (femML) effort is addressing the problems of data interpretation and application interoperability in the Finite Element Modeling domain. femML is an XML-based language for describing finite element models and associated results for inter - and intra- application data exchange and integration.
