Hi,
I have been trying to run the neutron star collapse simulation, using the par file /Cactus/par/arXiv-1111.3344/collapse/tov_collapse_vc_l3.par. I realised that it requires thorns from the Zelmani arrangement, and hence made an attempt to download them
I added the following lines to the thorn list, following < https://einsteintoolkit.org/publications/2013_MHD/einsteintoolkit_plus_zelma...
:
*# Private thorns!TARGET = $ARR!TYPE = svn!AUTH_URL = https://svn.einsteintoolkit.org/incoming/$2 https://svn.einsteintoolkit.org/incoming/$2!URL = http://svn.einsteintoolkit.org/incoming/$2 http://svn.einsteintoolkit.org/incoming/$2!CHECKOUT = Zelmani/CartesianCoordinatesZelmani/ZelmaniQuadWaveExtractZelmani/CoreCollapseControl*
Out of theses,ZelmaniQuadWaveExtract and CoreCollapseControl downloaded successfully, but CartesianCoordinates gave the following error:
*Warning: Could not checkout module Zelmani/CartesianCoordinatessvn: URL 'http://svn.einsteintoolkit.org/incoming/CartesianCoordinates http://svn.einsteintoolkit.org/incoming/CartesianCoordinates' doesn't exist.*
Since the neutron star collapse simulation uses a parfile distributed with the Einstein Toolkit release, I assume the thorns are available to the public. Is there any updated link for checking out the Zelmani arrangement thorns?

Hello Soham,

Zelmani itself is not in the public. However CartesianCoordinates is part of CTGamma (which is public and GPL) which you can download here:
git clone https://bitbucket.org/llamacode/ctgamma.git
or by adding this stanza to your thornlist:
!TARGET = $ARR !TYPE = git !URL = https://bitbucket.org/llamacode/ctgamma.git !REPO_PATH= $2 !CHECKOUT = CTGamma/CartesianCoordinates
Last time I tried it, the parfile was difficult to get to work though, unfortunately. You may have to play in particular with the method to reduce the pressure support initially.
Yours, Roland
Hi Roland,
Thank you for your help. I was able to download CartesianCoordinates using GetComponents. Thanks for the heads-up on the NS simulation. I will see if I can get it to work.
Sincerely, Soham

Hi,
This is actually not the case. Many thorns have examples which make use of other thorns which are not part of the toolkit. This is because the toolkit is an aggregation of existing components, each of which may have an independent existence, rather than a single monolithic project.
Having said that, a number of these uses of non-ET thorns are purely historical, for example BSSN_MoL, and those example parameter files should be updated to work with thorns which are part of the toolkit as much as possible. This is probably a low priority for the community however (if it is important for someone, please create a ticket; I can't find an existing one).
More important is that the examples that use only ET thorns actually work. The state as of the last ET workshop in the summer is reported at https://docs.einsteintoolkit.org/et-docs/Fixing_examples. We have 226 example parameter files, of which 36% run successfully, 39% depend on non-ET thorns, and 25% fail for some reason. We do not test the example parameter files automatically or on each release, which is probably why they have not kept up with developments in the toolkit.
