#2546: CarpetIOHDF5: Don't set "delta" attribute to zero for zero-width components

Reporter: Erik Schnetter Status: new Milestone: Version: development version Type: enhancement Priority: minor Component:

Carpet’s HDF5 format outputs a `delta` attribute that describes the grid spacing for each written chunk. Currently `delta` is always set to zero for zero-width components, i.e. e.g. for 2d arrays. This confuses post-processing tools.

This pull request passes the actual grid spacing to the writer routine, and writes the correct grid spacing into the attribute.
