Alright, I&#39;ll take a look.<div><br></div><div>But, I should emphasize that when I open each individual data file, sum the particle masses, and plot, the total mass increases monotonically over time, and agrees well with the decrease in gas mass.

Hi Munier,<br>
<div><br>
&gt;      Here is the cumulative mass, plotted from the same three data files.<br>
&gt; It&#39;s clear particles are being lost ...<br>
<br>
</div>Aha! That is kind of what I was suspecting! So this looks like it<br>
might be an Enzo problem. I&#39;d recommend trying to figure out what<br>
happened there. Perhaps there was an error during a restart or somehow<br>
two different simulations got mixed up? Good luck!<br>
