While the assigned values for the parameters
IOASCII::output_symmetry_points = "no" IOASCII::out3D_ghosts = "no" IOASCII::out3D_outer_ghosts = "no"
work as intended when CarpetIOASCII is active, it doesn't work for CarpetIOHDF5:
IOHDF5::out3D_ghosts = "no" IOHDF5::out3D_outer_ghosts = "no" IOHDF5::output_symmetry_points = "no"
It doesn't do anything to the 3D data but it corrupts the 2D data slices while chopping out those regions. It would be nice to have them working for IOHDF5 method, specially when visualising Pi symmetric data.
Note also that this report is for git version of Carpet. These parameters seem to become deprecated for the hg version. Does anyone use them regularly? Any substitute in mind?
