Hi,

    I have a chance to re-test all the HDF5 and XDMF files with Paraview 
3.8.1 on Ubuntu 10.04 64bit.

    No problems at all.

    So all my issues with using XDMF to display HDF5 is a problem with 
the build of Paraview 3.8.1 on OSX 10.5 (PPC)

    Thank you for the tip on structuring XDMF files.

Regards
