<div dir="ltr"><div dir="ltr"> Hello everyone,<div><br></div><div>I am still trying to run the arXiv-1111.3344 TOV collapse simulation and having continued issues with updating the thornlist, specifically CoreCollapseControl. </div><div><br></div><div>Specific questions:</div><div>1. After updating my thornlist with CoreCollapseControl, my Cactus rebuild fails while compiling CoreCollapseControl, citing a few undeclared variables warnings before a final "Error 2." Am I missing a step in the update process?</div><div><br></div><div>2.
Per Roland's previous email, I attempted to find CartesianCoordinates in the Llama repository but it does not exist. Has it been absorbed/replaced by the Coordinates thorn? And, if so, should I simply replace "CartesianCoordinates" with "Coordinates" in the par file?</div><div><br></div><div>3. With the known issues with the TOV collapse simulation, are there any recommendations for another collapse simulation? I am just looking for a working code shell and am not particularly tied to TOV.</div><div><br></div><div>Please see below for the steps I took to update my thornlist and build a new experimental Cactus configuration. I have also attached a log file with the output from my build.</div><div><br></div><div>1. For CoreCollapseControl:</div><div> a. I made a new repository called corecollapse and checked out the thorn into Cactus/repos/corecollapse using:</div><div><br></div><div><b>svn checkout <a href="https://svn.einsteintoolkit.org/incoming/CoreCollapseControl/">https://svn.einsteintoolkit.org/incoming/CoreCollapseControl/</a></b><br></div><div><br></div><div> b. I created Cactus/arrangements/corecollapse then inside of it created a soft link to Cactus/repos/corecollapse/CoreCollapseControl</div><div><br></div><div> c. I added the following lines to my thornlist:</div><div><br></div><div><b>!TARGET = $ARR</b></div><div><b>!TYPE = git</b></div><div><b>!URL = <a href="https://bitbucket.org/einsteintoolkit/tickets/issues/1358/import-corecollapsecontrol-into-et">https://bitbucket.org/einsteintoolkit/tickets/issues/1358/import-corecollapsecontrol-into-et</a> </b></div><div><b>!REPOPATH = $2</b></div><div><b>!Checkout = </b></div><div><b>corecollapse/CoreCollapseControl</b></div><div><br></div><div> e. Built a second experimental configuration called sim2 from within Cactus directory with:</div><div><br></div><div><b>sim build sim2 --thornlist ./thornlists/<a href="http://einsteintoolkit.th">einsteintoolkit.th</a></b></div><div><br></div><div>Once again, thank you ahead of time for any help!</div><div><div><br></div>-- <br><div dir="ltr" class="gmail_signature"><div dir="ltr">Kindest Regards,<div><br></div><div>Justin Verde</div></div></div></div></div><div><br></div><div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Jan 24, 2020 at 2:17 PM Haas, Roland <<a href="mailto:rhaas@illinois.edu">rhaas@illinois.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hello Justin,<br>
<br>
those were some thorns that were private at the time.<br>
<br>
CoreCollapseControl has been proposed for inclusion in this ticket:<br>
<br>
<a href="https://bitbucket.org/einsteintoolkit/tickets/issues/1358/import-corecollapsecontrol-into-et" rel="noreferrer" target="_blank">https://bitbucket.org/einsteintoolkit/tickets/issues/1358/import-corecollapsecontrol-into-et</a><br>
<br>
and you can obtain a copy using svn:<br>
<br>
svn checkout<br>
<a href="https://svn.einsteintoolkit.org/incoming/CoreCollapseControl/" rel="noreferrer" target="_blank">https://svn.einsteintoolkit.org/incoming/CoreCollapseControl/</a><br>
<br>
CartesianCoordinates is part of Llama and in the llama repository that<br>
has since become part of the Toolkit.<br>
<br>
So you can use it by adding a line like this:<br>
<br>
Llama/CartesianCoordinates<br>
<br>
to your ThornList. You may have to create the appropriate symbolic link<br>
first via (something like):<br>
<br>
cd arrangements/Llama<br>
ln -s ../../repos/llama/CartesianCoordinates CartesianCoordinates<br>
<br>
TriggerTerminationManual has been superseeded my the TerminationTrigger<br>
thorn (in CactusUtils) in the toolkit, though you can also just comment<br>
it out since it does not affect physics.<br>
<br>
Even with all those in place, the TOV collapse is "temperamental" and<br>
sometimes does not work well.<br>
<br>
Please see here:<br>

<br>
for someone else's experience.<br>
<br>
Basically Tony had to increase resolution by a factor of 2 (to 1.6<br>
from 3.2) to avoid failures.<br>
