GetDP is a rather general open source finite element solver using mixed elements to discretize de Rham-type complexes in one, two and three dimensions. GetDP is developed by the ACE group from the Montefiore Institute at the University of Liège, and is released under the GNU GPL.

Getting started
ONELAB allows to use GetDP as a black-box solver: you don't need to know anything about finite elements or de Rham complexes in order to run your first simulations:
- Download the latest nightly build of Gmsh for Windows, MacOS X or [Linux
- Download the latest nightly build of GetDP for Windows 32 bit/64 bit, MacOS X 32 bit/64 bit or Linux 32 bit/64 bit
- Uncompress the 2 archives (there is no installation necessary ; you can move them to any directory you want)
- Double-click on the Gmsh executable (gmsh.exe on Windows) ; a graphic window and a command window will open
- Load one of thé geometries through the 'File->Open' menu (e.g. the file Transfo.geo for the transformer example below) ; the geometry will appear in the graphic window
- Go to the 'Solver' module (by clicking on the 'Geometry' button in the command window, then selecting 'Solver')
- Click on thé 'GetDP' button
- The first time you you will specify the location of the GetDP executable (getdp.exe on Windows) on your hard drive (this depends on where you uncompressed the archives in step 2.)
- Change some parameters in the ONELAB window and click on 'Compute'
- ... that's it!
