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.html https://einsteintoolkit.org/thornguide/Carpet/CarpetIOASCII/documentation.html though only the CarpetIOASCII thorn actually documents the option. For CarpetIOHDF5 you have to consult its param.ccl file https://bitbucket.org/eschnett/carpet/src/master/CarpetIOHDF5/param.ccl Yours, Roland -- My email is as private as my paper mail.
