Purpose
Thorn IOHDF5 uses the standard I/O library HDF5part781to output any type of CCTK grid variables (grid scalars, grid functions, and grid arrays of arbitrary dimension) in the HDF5 file format.
Output is done by invoking the IOHDF5 I/O method which thorn IOHDF5registers with the flesh's I/O interface at startup.
Data is written into files named "<varname>.h5". Such datafiles can be used for further postprocessing (eg. visualization) or fed back into Cactus via the filereader capabilities of thorn IOUtil.
