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 builds of Gmsh (for Windows, MacOS X or Linux) and GetDP (for Windows 32 bit/64 bit, MacOS X 32 bit/64 bit or Linux 32 bit/64 bit)
- Uncompress the 2 archives (no installation necessary; you can move them to any directory)
- Double-click on the Gmsh executable (gmsh.exe Error creating thumbnail: Unable to save thumbnail to destinationon Windows); a graphic window and a command window will open
- Load one of the geometries through the File->Open menu (e.g. the file magnet.geo for first 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 the GetDP button (the first time you you will need to specify the location of the GetDP executable, e.g. getdp.exe on Windows; this depends on where you uncompressed the archives in step 2.)
- Click on Compute
- ... that's it!
Simple examples (just unzip) :

Electromagnetics
Acoustics
Time harmonic acoustic scattering (Helmholtz equation)
- Multiple scattering with Sommerfeld absorbing condition
- Multiple scattering with a Perfectly Matched Layer (PML)
Heat transfer
Generic PDEs
The following examples explain the fundamental concepts used in GetDP '.pro' files
