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:

1. Download and uncompress the Gmsh/GetDP bundle for Windows64, Windows32, Linux64, Linux32 or MacOSX. (If you prefer you can of course also download and install Gmsh and GetDP independently. Please note that the examples below require very recent versions of Gmsh and GetDP, i.e., nightly builds made after December 4th, 2013. Current stable versions will not work.)
2. Double-click on the Gmsh executable (gmsh.exe
   Error creating thumbnail: Unable to save thumbnail to destination
   on Windows).
3. Load one of the GetDP models (.pro file) through the File/Open menu, e.g. inductor.pro for the simple inductor/core example.
4. Click on Run.
5. ... that's it!

On Windows, depending on your computer security settings, you might have to explicitly allow the GetDP executable (getdp.exe) to be launched by Gmsh. Manually launch GetDP once by double-clicking on getdp.exe to allow this.

• 

  Launch Gmsh and load the GetDP model magnet.pro with the File/Open menu.

  Click on Run to launch a computation. You can change any parameter and then Run again!

How does it work?

GetDP input files (.pro files) can be instrumented to share parameters with the ONELAB server, through the same syntax as the one used in Gmsh.
