[Users] Fwd: SphericalSurfaces + QuasiLocalMeasures + AHFinderDirect

[Samuel Tootle]

Hi Leo,

I actually have the same test for the FUKA importer using a single BH.  
The par can be found with the KadathImporter thorn or directly here:

Cheers,

Samuel

The goal is to set up puncture initial data with NRPyEllipticET and then use QuasiLocalMeasures/AHFinderDirect to compute properties of the punctures and compare with the expected results. No evolution thorn is expected/required and the simulation ends after the initial data has been set and the first round of analysis has finished.

However, the diagnostics are clearly wrong since: 1) AHFinderDirect fails to find the puncture (in this example I am setting the mass of one of the punctures to zero); and 2) the QuasiLocalMeasures diagnostics is never triggered, despite being scheduled.
