<div dir="ltr">Hayley<div><br></div><div>The simplest way would be to post-process the HDF5 files after the simulation has finished. HDF5 comes with tools that manipulate HDF5 files, e.g. adding/removing compression, and also copying or selecting objects from one file to another. You can also use this to combine output from all processes into a single file. For post-processing, having one file per variable (!) and iteration is often the most convenient.</div><div><br></div><div>-erik</div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Jun 20, 2017 at 9:04 AM, Hayley Macpherson <span dir="ltr"><<a href="mailto:hayley.macpherson@monash.edu" target="_blank">hayley.macpherson@monash.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto">Hello,</div><div dir="auto">I am using the Einstein Toolkit for cosmological simulations, and would like to ask a question regarding my HDF5 3D output. </div><div dir="auto">Currently I am outputting all 3D snapshots to one HDF5 file (as per default).
