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.
DOUG Download
DOUG is a black box parallel iterative solver for finite element systems arising from elliptic partial differential equations. Used in conjunction with a finite element discretisation code, DOUG will solve the resulting linear systems using an iterative method and provides a range of powerful domain decomposition preconditioners. Will run in parallel on any machine which supports MPI. Has been tested on SGI, SUN, SUN Solaris, IBM SP/2 and Intel i860 architectures. DOUG makes no assumptions about the FE mesh: it takes as input basic topological information (eg from a mesh generator), and the finite element discretisation (stiffness matrix and RHS for each element). DOUG then applies a range of domain decomposition preconditioners and iterative methods to solve the linear system.
Deal II Download
A C++ program library targeted at adaptive finite elements and error estimation. deal.II has been developed on Unix systems (including Linux) using the gcc2.95x compiler. Installation on other platforms should not be difficult. Multi-processor machines are also supported. The C++ source code is freely available for research purposes under an Open Source license. The gzipped tar file may be downloaded through the deal.II homepage. Object oriented programming techniques which encourage logical representation of mathematical structures are combined with fast algorithms which can solve problems with up to several million dof. deal.II provides extensive documentation in HTML format and includes a tutorial introduction, interface documentation and several papers. A mailing list is available.
ALBERT Download
ALBERT is an Adaptive multiLevel finite element toolbox using Bisectioning refinement and Error control by Residual Techniques. Platforms include: Linux, and UNIX based workstations from DEC, HP, SGI, and Sun. Requires BLAS. OpenGL (or Mesa) is recommended.
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.
