The Free Finite Element Package is a modular designed collection of GNU Octave / MATLAB functions in a library. This library contain numerical methods required when working with linear Finite Elements in two dimensions. FFEP is tested using GNU Octave (primarily) and MATLAB (second-tier).
With the Finite Element Method (FEM) (Wikipedia Article) it is possible to solve partial differential equations (PDE) (Wikipedia Article). See under the section About for further details.
Right now version 1.0 is available. The software was mainly designed for teaching purpose. You should consider this before using FFEP! To contact the developer write a mail to joerg @ frochte . de or joerg . frochte @ hs - bochum . de.
Until 2016 FFEP was developed using C. Science 2016 the language was switched to GNU Octave with some C Mex-Functions. Mesh generation or import is not part of FFEP. We recommend the use of Gmsh.
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.
