But of course, you would be the first H5block "user".
It'll be interesting to see if it meets your needs. :-)

I think H5Block provides the capability that you are looking for. It provides the ability to store the block-structured grids that are associated with the PIC calculation together with the particle data.

The H5Block interface should automatically re-integrate the chunks (the 64 volumes) into the single/un-domain-decomposed logical volume used in the calculation.

I've been happily using H5Part particles for some time, but I need to write a bunch of volume chunks into HDF as well.
I have (say) 64 volumes which abut each other - the points along the edges are not duplicated (0->7, 8->15, 16->23, 24->31 etc etc). I was about to start a little utility to dump these volume chunks into hdf files and I thought. I wonder if this is what H5Block does?

What is H5Block ? I have not looked at it at all (yet).

thanks
