Hello Hassan,
the level 1 warnings from CarpetRegrid2, while not something that every single run produces, are not unusual. The code there uses an iterative scheme to enforce some constraints and while we typically expect that one round of enforcement is enough, there can be interactions between the different constrains that require more than one round. The level 1 warning tell you that indeed a second round was required. This enforcement happens infrequent enough and is fast enough that it does not affect your simulation run speed.
By "Carpet attempts to do so ten times, then gives up assuming there is an internal inconsistency" Erik meant that if it need more than 10 rounds for a *single* instance of the constrain enforcement, then it gives up. In your case you see multiple instances of the constrains enforcement (once for each time that eg a neutron star moved far enough that Carpet has to move the computation grid patches to keep the star roughly centered on its grid patch).
You may want to visualize some of the data in VisIt or similar (2d slices in the xy plane are enough) just to check that eg the grid (shown via a "Mesh" plot in VisIt) nicely follows the stars (eg via the HydroBase::rho variable).
Yours, Roland
Hello All,
The simulation is running for about 23 hours, and the warning below is showing up repeatedly. Is it normal ?
I saw in archived emails about CarpetRegrid2 Warnings, that Erik mentioned that : "Carpet attempts to do so ten times, then gives up assuming there is an internal inconsistency"
But here it is still processing. and the warning had shown up for about a hundred times!

Dear Roland Thank you for your prompt response. The simulation is still going on and there is no level 0 warning.
Hello Hassan,
all warnings that are level 1 and higher can be ignored (high level means a lower priority warning).
Only level 0 are actually errors. Level 2 and higher are usually "stuff that we'd want to let you know but that will not cause any averse effects", such as the " No HDF5 checkpoint files with basefilename 'checkpoint.chkpt' found" that is output for the first segment of a simulation.
The one "Could not register parameter change monitor for 'signal_numbers'" is a bit more puzzling since this should not happen (it is perfectly harmless though).
Does your simulation actually proceed or does it abort with a level 0 warning or similar issue?
Yours, Roland
Dear all,
I need some guidance on reproducing the NsNsToHMNS which is provided in the gallery section of ET's website. but there are a bunch of warnings during the simulation.
I would be grateful if anyone could possibly tell me what is the minimum limit on core numbers for the NsNs and also check the warnings below.
I tried with 4 procs at first , but now I am trying on 28 procs. but there are same warnings. I don't know if I have to take them serious or not ! Because even with these warnings, the simulation is still running...
Gratefully, Hassan
