[Users] issue with Outflow after BHB merger

[Federico Cattorini]

Dear all,

I am having issues with the thorn Outflow running a BHB simulation with
WhiskyMHD (parfile attached). Outflow correctly computes the flows on the
single orbiting BHs during the inspiral, but after the merger it fails to
compute it on the newly formed BH.
I get the following warning in the .out:

WARNING level 1 from host r149c18s02.marconi.cineca.it process 0
  while executing schedule bin CCTK_ANALYSIS, routine Outflow::outflow
  in thorn Outflow, file
/marconi/home/userexternal/fcattori/EinsteinToolkit/ET_2018_09/Cactus/arrangements/EinsteinAnalysis/Outflow/src/outflow.c:958:
  -> didn't find valid detector surface for sn=2, det=2

In my parfile I implement Outflow as

outflow::compute_every        = 64
outflow::num_detectors        = 3
outflow::surface_index[0]     = 0
outflow::surface_index[1]     = 1
outflow::surface_index[2]     = 2
outflow::interpolator_name    = "Lagrange polynomial interpolation"
outflow::interpolator_pars    = "order=4"

AHFinderDirect uses three spherical surfaces (n. 0,1,2). PunctureTracker
tracks and write its values on n. 0 and 1.

Does anyone know how to address this issue?

Thanks a lot,

Federico
