#1682: New thorn CactusExamples/Poisson -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- I suggest to include the thorn CactusExamples/Poisson into the Einstein Toolkit. This thorn solves the Poisson equation, i.e. an elliptic equation, using the TATelliptic interface. A sample parameter file uses PETSc as back-end (via the generic TATelliptic interface).

Comment (by knarf):
The thorn does not contain a testsuite. Would this be feasible, even (or maybe especially) for an example thorn? This connects to the example parameter file, so please see below:
The example parameter file (as advertised) needs PETSc. This is not a big problem, as all required thorns are in the ET, but we have to remember that these are disabled for 'regular' installations.
Speaking of the example parameter file: the output contains nans in the residuum, in particular in the boundary zones - but these spoils the reduction values too.

Could we have a little bit of documentation?

Done. And done.
Added to Einstein Toolkit.
