FreeFEM, FreeFEM+, FreeFEM++, FreeFEM3D Download
|
|
|
| The FreeFEM* programs are a family of open source adaptive FE codes which can be applied to solve a variety of pde's and pde systems. Platforms:
The program has been compiled on the Macintosh and Powermac, on PC's running Windows 3.1 and Windows 95, and on a variety of work stations (Sun, HP, IBM RS6000 etc). Windows and Mac executables are provided, otherwise compile from source.

Free Finite Element Package Download
|
|
|
| The Free Finite Element Package is a modular designed collection of C libraries. These libraries contain numerical methods required when working with linear and quadratic Finite Elements in two dimensions.
FFEP should meet the following requirements:
The Package should be easy to be used, well documented, stable, fast, portable and last but not least Open Source Software.
The required dense matrix and vector operations of the package are based on LAPACK and CBLAS. For more details of LAPACK and CBLAS see Related Links. The memory management, the interfaces to the CBLAS and LAPACK functions and some additional functionality are combined in the Meta Matrix Library, which can be used for numerical projects without the rest of the Library-Collection.

FEMM Download
|
|
|
| FEMM - Finite Element Method Magnetics - is an FEA solver for low frequency 2D and axisymmetric magnetic problems. Includes preprocessor and postprocessor. Uses Triangle (qv) for meshing. Can import DXF files. Freeware. The source code is available. Microsoft Visual C++ (version 4 or higher) is required to compile it. The manual can be compiled with pdfTeX. FEMM now incorporates the Lua scripting language to allow the user to perform batch runs.
An additional service related to the program is now available: professional support and consultancy services for the program are now available for FEMM through Foster-Miller.

FemLisp Download
|
|
|
| Femlisp is an interactive framework for solving partial differential equations with the help of the finite element method (FEM), written completely in Common Lisp. It can handle Lagrange finite elements of arbitrary order on unstructured meshes of arbitrary dimension. Femlisp is known to work on Linux with the free Common Lisp implementations CMUCL and SBCL, on Solaris with CMUCL, and on Mac OS X with SBCL. It should be easy to port to Windows with commercial implementations of Common Lisp (Allegro CL, Lispworks, Corman Lisp).

FEM2DLib Download
|
|
|
| FEM2DLib is a Fortran-90 module with set of data structure definitions (that behave more or less as "objects"), functions and subroutines that can be used to solve simple problems with ordinary and partial differential equations using the Finite Elements Method (FEM).
In its simplest applications FEM2DLib requires only a problem definition file (mesh, material functions etc) and about 10 lines of Fortran code. Experienced Fortran programmers can solve complex 2D problems which may involve time-dependent boundary conditions, time-dependent mesh structures, or changing mesh resolutions over advected features.
FEM2DLib can solve transient and steady state advection-diffusion problems. The library contains several types of elements (1D elements, triangular elements, directly integrated or isoparametrical with up to 9 nodes and rectangular serendipity and lagrange elements, with up to 9 nodes). The data structures are allocated dynamically, so the limit to the size of a mesh is imposed only by the amount of virtual memory available. Any platform that supports a ANSI-standard Fortran-90 co mpiler
