Hello Steve,
As a newer to Einstein Toolkit, I have successfully finished and executed the example file in the server following the link: https://github.com/nds-org/jupyter-et/blob/master/CactusTutorial.ipynb. But I have a question about deciding the simulation output directory，how can l give the self-defined output directory for storing the simulation results. Is there any files contents or commands inside ET that could define the output directory by myself, or any documentations clarifying how the Einstein Toolkit decide the IO directory?
Maybe it is a simple question, but I really don’t want to mess the common folders up too much, since I need to work out some simulations about NR in the group’s server.
Cactus thorns take the output directory for their output from the parameter
IO::out_dir
(an alternative name is IOUtil::out_dir)
in the parameter (*.par) file. Some thorns eg CarpetIOHDF5 let you specify that for their output you would like a different directory, however they default to IO::out_dir. Eg
CarpetIOHDF5::out3d_dir
This is described in the documentation of the IOUtil thorn (which provides the IO options):
https://einsteintoolkit.org/thornguide/CactusBase/IOUtil/documentation.html
and in CarpetIOHDF5 / CarpetIOASCII etc:
https://einsteintoolkit.org/thornguide/Carpet/CarpetIOHDF5/documentation.htm... https://einsteintoolkit.org/thornguide/Carpet/CarpetIOASCII/documentation.ht...
though only the CarpetIOASCII thorn actually documents the option. For CarpetIOHDF5 you have to consult its param.ccl file

Yours, Roland
