<p>Dear who it may concern,</p>
<p>I have tried the binary neutron star simulation (<a href="http://einsteintoolkit.org/gallery/bns/index.html" class="OWAAutoLink" id="LPlnk888693" previewremoved="true">http://einsteintoolkit.org/gallery/bns/index.html</a>), and want to finish the simulation
by parts .That is , I would like to recover the simulation from checkpoints. However I fail to continue my simulation. There are two cases that I met:</p>
<p></p>
<ol style="margin-bottom: 0px; margin-top: 0px;">
<li><span style="font-size: 12pt;"></span>I have the cctk_final_time=2500 and the simulation terminate at time=2500 but the merge has not yet occur which means I need more time ,perhaps <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;">time=8000.
So I want to continue my simulation from time=2500. But after I changed to <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;">cctk_final_time=8000
in parameter file , the simulation still stops at time=2500, which means it stops just after it begins. How can I finish the complete simulation?</span></span></li><li><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;"><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;">I
have test the same simulation as above but with wall_time=10 min. I have checkpoint_every=150 ,and checkpoint_on_terminate= "yes" in the parameter file. However after it finishes with the final iteration=250, the checkpoint file is not produced. Only the initial
one <span>checkpoint.chkpt.it_0.file_0.h5 exists. How can I produce a <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;">checkpoint
which enable me to restart simulation?</span></span></span></span> <br>
