San Le's Free Finite Element Analysis Download
A freely available finite element package, with 2D and 3D structural analysis capability. Platform: Linux or other UNIX platform. Requires a C compiler and MESA or similar GL or OpenGL library. PERL is recommended.



PSU Download
PSU (Proze?Simulation in der Umformtechnik) utilises modern FE techniques to solve general field problems, in particular those with geometrical (large deformation, contact) and material non-linearities. Fields include 1-3D mechanical, thermal, electric, coupled. It is particularly well-suited to research problems, both academic and industrial.



PLTMG Download
Solves 2D elliptic Boundary Value Problems (BVP's) by the FE method.



PARSYS Download
PARSYS is a general numerical FE code which solves one or more one-dimensional non-linear parabolic PDE's of the form dU(x,t)/dt = (P1(U,dUdx,x,t)U'(x,t))' + (P2(U,dUdx,x,t)U(x,t))' + P3(U,dUdx,x,t)U(x,t) + F(U,dUdx,x,t) by up to 12th-order FE in space. The number of equations is a variable parameter which is given by the user. In time, explicit Euler scheme and higher-order adaptive implicit schemes based on the Backward Difference Formula contained in ODEPACK, are implemented.



ParaFEM Download
ParaFEM is a parallel finite element code using MPI. Platforms: Written in Fortran 90/95. Binaries available for SGI, Windows, and Linux.



OFELI (Object Finite Element LIbrary)
An Object Finite Element LIbrary of C++ classes for the development of finite element codes. Platforms: The C++ source code compiles on Unix and Windows systems. The OFELI library includes mesh manipulation tools, a variety of matrix storage schemes, direct and preconditioned iterative solvers, a range of shape functions, element arrays for standard problems, and classes for standard formulations (transient, non-linear etc). Documentation is provided.



Nonlinear Finite Element Toolbox (NLFET) Download
NLFET is a nonlinear finite element toolbox for MATLAB released under the GNU General Public License (GPL). The toolbox provides a framework for setting up, solving, and interpreting results for nonlinear static and dynamic finite element analysis.



NIST Modelling Programs Download
The Computational Materials Science of Concrete Laboratory at the National Institute of Standards and Technology have developed a number of finite element / finite difference programs applied to composite material models.
