<p>Hi Roland,</p>
<p><br>
</p>
<p>Thank you again for your reply, for the explanation and the
paper. I was not aware of the use of buffer points related to
time integration substeps.</p>

<span style="white-space:pre-wrap"></span> I am looking at HDF5
output, and I have the default "yes" for
IOHDF5::output_ghost_zones. I tried to change it to "no" but this
did not change this feature of the output. </div>

<div

<p>I think it is, thank you! I'm still a bit puzzled by the fact
that I don't get 4*ghost_size points as you explained, but for
now, I think it is enough for me to understand where these
"extra" points come from.</p>
