Does it matter if the cells I add come after those ghost cells, or should the ghosts always come last?<br>
<br>
It seems to me it probably shoudn't matter if the partition ghosts (created by DMPlexDistribute()) are not at the end. In my cell loops I just check the value of the ghost DMLabel and skip them if necessary.<br>
<br>
But perhaps the boundary ghosts (created by DMPlexConstructGhostCells()) need to come last? Otherwise the output from DMPlexGetHybridBounds() (to get the bounds on 'interior' cells, i.e. non-boundary-ghosts) probably wouldn't make much sense?</blockquote><div><br></div><div>Yes, the only reason to have them last is to have GetHybridBounds() work for that case.</div><div><br></div><div> Thanks,</div><div><br></div><div> Matt</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="HOEnZb"><font color="#888888"><br>
