<p>Dear whom it may concern,</p>
<p>I am trying to reproduce the simulation of binary neutron star (<a href="http://einsteintoolkit.org/gallery/bns/index.html" class="OWAAutoLink" id="LPlnk745505" previewremoved="true">http://einsteintoolkit.org/gallery/bns/index.html</a>) with different mass.
I use Lorene code to produce the initial data . The parameter files I used is locate in <span>/Lorene/Codes/Bin_star/Parameters/Polytrope_irrot/Test_GR . And I changed central enthalpy of each star
<span style="font-family: Calibri, Helvetica, sans-serif, Helvetica, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
in par_init.d </span>to get different mass (Is there other way I can get different mass?). And then I simulate with the ET. However I met some problems:</span></p>
<p><span>1.I requested 48 cores with 10 hours to run the code , however the code terminated after running ~4 hours. And the end of .err file reads:</span></p>

<p>The code is aborted without completing the whole process until the merger. How can I perform the complete process?</p>
<p>2. When I use visit to do the visualization ,I found the file rho.xy.h5 only has half of the whole simulation as :</p>
<p><img size="89378" contenttype="image/png" id="img455277" contextid="img13097" tabindex="0" style="max-width: 99.9%; user-select: none;" src="cid:e66a53d5-d406-4599-997f-00e90a864dc0"><br>
<br>
</p>
<p><br>
</p>
<p><br>
</p>
<p><br>
</p>
<p>The tutorial(<a href="http://einsteintoolkit.org/gallery/bns/scripts.tar.gz" style="box-sizing: border-box; background-color: rgb(204, 225, 255); color: rgb(51, 122, 183); text-decoration-line: none; font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 14px; text-align: center;">scripts.tar.gz</a>)
tells that I should use symmetric reflection to perform the whole visualization. However I cannot use this method since I simulated binary star with different mass . So there is no symmetry. How can I get the whole picture instead of only half ? </p>

<p>Thank you.</p>
