IOHDF5 Output Restrictions

Due to the naming scheme used to build unique names for HDF5 datasets (see J2.8, the IOHDF5 I/O method currently has the restriction that it can output a given variable (with a specific timelevel) - or a hyperslab of it - only once per iteration.

As a workaround, you should request output in such a case by using the flesh's I/O API CCTK_OutputVarAsByMethod() routine with a different alias name for each output. Note that this will create multiple output files for the same variable then.
