Hi all,
I am starting to learn the use of CarpetX and for this I started using the
WaveToyX thorn. I wanted to ask for guidance for three problems that I have
encountered so far, all of them related to the output data:
1) I wanted to get 3D data, for example in .tsv format. Here I realised that
there is an ambiguous definition in the documentation for the parameter
“out_tsv”, which in section 12.1 it says to control TSV output and have default
value “yes”, but in section 14 it says to control the 3D output in TSV and have
default value “no”. This last behaviour is the one that I encounter when
running the parfiles.
2) When I set up “out_tsv" to “yes” and “out_tsv_every” to a number, for
example = 16, I get 1D output every 16 iterations, but 3D output in every
iteration, therefore I suspect that “out_tsv_every” is only controlling the
frequency of the 1D output, and I cannot find a way to control the frequency of
3D output.
3) I attempted to output data in HDF5 format but I did not succeed. I first set
the parameter “openpmd_format” to “HDF5” and also set “out_openpmd_vars” to the
variables that I wanted, but I got an error in the first iteration:
INFO (CarpetX): OutputGH: iteration 0, time 0.000000, run time 1 s

INFO (CarpetX): Creating openPMD object...

And I did not know how to move on from there.
I am working on the ETK Tutorial server, in case that is important.
Thanks in advance to anyone who took the time to read until here, I will be
looking forward to any piece of advice :)
Best,
