FEMOctave Download
This is a very simple FEM package for Octave. It solves second order differential equations in two variables, using first order elements.
FEATFLOW
FEATFLOW is a Finite Element program for the solution of the incompressible Navier-Stokes equations. It includes the Finite Element subroutine libraries FEAT2D and FEAT3D. Platforms: Fortran 77 source code. Installation for several UNIX variants (SunOS, Solaris, AIX, IRIX, and Linux) available.
Code Aster Download
Code_Aster is a general purpose finite element code released under the GNU General Public License. Platforms: Solaris, HP-UX, IRIX, Windows NT. Available from the Code ASTER web site. (Note: this web site is in French, look for ``Telechargement'' for download area.) Requires Python and TCL to install, as well as a Fortran compiler.
CalculiX Download
A 3D structural analysis FE program. CalculiX is available under the terms of the GNU public license. The CalculiX package includes a pre/post processor (GraphiX:cgx) based on hexahedral elements, and the solution engine (CrunchiX:ccx). Models with up to 150,000 df have been analysed. Finite element capabilities include linear and non-linear (material, geometric) static and dynamic analysis, buckling and frequency analysis. Material models include linear elastic, hyperelastic, deformation plasticity and incremental plasticity. Further extensions (heat transfer, viscoplasticity, contact/frictional boundary conditions) are planned.
ALADDIN Download
ALADDIN is a computational toolkit for matrices. ALADDIN views Finite Element Analysis as a specialised matrix computation. ALADDIN is being developed at the Institute for Systems Research, University of Maryland, College Park, USA, under the financial sponsorship of the Federal Highway Administration and the National Science Foundation. ALADDIN includes a mesh generation package. The ALADDIN finite element library currently comprises elements for plane stress/strain, 2D beam/column analysis, 3D truss analysis, DKQ plate analysis, and a variety of shell finite elements. ALADDIN has been tested on a SUN SPARCstation, DECstation 5000, and IBM RS/6000.
