Registration open for NR community calls in the Fall
by Nils Vu 18 Aug '23

18 Aug '23

Dear Numerical Relativists, A new season of NR community calls is approaching! Registration is now open to present at one of the calls starting on Sep 11, 2023. Please sign up here: - Request a slot to present at the NR community calls: https://github.com/sxs-collaboration/nr-community-call/wiki The NR community call is a monthly meeting to foster exchange between our numerical-relativity groups and codes. We usually have two speakers from different groups give brief (10-15min) talks, often on a technical aspect of the numerical-relativity code that they are working with, presenting what works well and what they are struggling with. The talks are followed by 15min of discussion. The speakers are preferably early-career researchers, so the calls are also a good opportunity to increase your visibility to our community. As always: - Feel free to circulate this information within the NR community. - Please subscribe to our mailing list <https://groups.google.com/u/1/a/black-holes.org/g/nr-community-call/> to receive info on the community calls in the future (or send a short message to nr-community-call+subscribe(a)black-holes.org <mailto:nr-community-call+subscribe@black-holes.org> to subscribe) and join our Slack <https://join.slack.com/t/generalrelativity/shared_invite/zt-dl4gqb6v-aAuw~p…> for discussions (channel: #nr-community-call <https://generalrelativity.slack.com/archives/C021LLTLK37>). - Details and schedule in the wiki: https://github.com/sxs-collaboration/nr-community-call/wiki Best, Nils — Nils Vu, Ph.D. (he/him) Sherman Fairchild Postdoctoral Fellow in Theoretical Astrophysics California Institute of Technology

Installing kuibit in Ubuntu 23.04
by CJ Osakwe 17 Aug '23

17 Aug '23

Hello, I'm not sure who to talk to about this, but I can't get the command to install Kuibit to work. I've been using the Einstein Toolkit for a few months now, and I wanted to update everything in light of the recent 'Schwarzschild' release. The toolkit itself was fine, but when I input the shell command to install Kuibit: pip install --user -U kuibit==1.4.0 I receive the following error message: error: externally-managed-environment This environment is externally managed ╰─> To install Python packages system-wide, try apt install python3-xyz, where xyz is the package you are trying to install. If you wish to install a non-Debian-packaged Python package, create a virtual environment using python3 -m venv path/to/venv. Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make sure you have python3-full installed. If you wish to install a non-Debian packaged Python application, it may be easiest to use pipx install xyz, which will manage a virtual environment for you. Make sure you have pipx installed. See /usr/share/doc/python3.11/README.venv for more information. note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages. hint: See PEP 668 for the detailed specification. I should mention that my version of Python no longer recognizes that kuibit is installed, i.e., when I run Python I get the error: ModuleNotFoundError: No module named 'kuibit'. This is what motivated me to update everything in the first place. Thanks, CJ Osakwe Ph.D. candidate, University of Calgary

Hi, I would like to know more physics about the single stable neutron star solved using the toolkit as part of my master's project. Would you be able to throw some light on this? And I have a question about the time scales used in this particular problem, they are of order 10^-6, usually, neutron stars are highly compact objects, In this problem, the density was of the order 10^-3 why are these scales chosen, and this paper said (https://arxiv.org/abs/1111.3344.) the spikes in the graphs are due to the interaction with the artificial atmosphere I would like to know more about it. I am attaching my results. Warm regards

Re: [Users] Error while running toolkit

Hello Thejas, > ADM base is already there, and I have updated the thorn list, > https://urldefense.com/v3/__https://einsteintoolkit.org/gallery/poisson/ind… I got the par file > from here. I may be that the file exists but as far as I can tell it is not listed in the thornlist that you are compiling. In the output to screen just after "Parsing configuration files" it lists all the thorns present in the thornlist you are compiling and that list (alphabetically sorted) does not contain ADMBase. You may need (if you use simfactory) to pass the --thornlist option or of not using simfactory set THORNLIST or edit configs/sim/Thornlist The gallery example gives a thornlist (ET Schwarzschild release (ET_2023_05)) that is known to work with the parfile. Have you tried that one? I am asking because using it with GetComponents and simfactory should really give you a working ADMBase. If all else fails I would suggest starting from scratch, that is remove your whole Cactus directory, run GetComponents and simfactory again as described on http://einsteintoolkit.org/download.html Yours, Roland PS: If possible, please keep the mailing list users(a)einsteintoolkit.org in the list of addressees so that the email thread stays visible. > > > On Tue, 1 Aug 2023 at 03:05, Roland Haas <rhaas(a)illinois.edu> wrote: > > > Hello Thejas, > > > > Sorry for the delay, I was busy with the ET summer school at RIT and a > > second meeting just afterwards 9best to cc users(a)einsteintoolkit.org > > on these emails so that others also see them and can jump in). > > > > Looking at the error message: > > > > --8<-- > > CST error in /home/thejas/Cactus/repos/flesh/lib/sbin/interface_parser.pl > > (at 273) > > -> CT_MULTILEVEL is friends with ADMBase - non-existent implementation > > --8<-- > > > > you are missing the thron ADMBase (in the EinsteinBase arrangement). > > > > You will need to update your thornlist file and add > > > > EinsteinBase/ADMBase > > > > to it.

I installed the toolkit 2023 version, and it showed an error: Parameter file: /home/thejas/Cactus/arrangements/CactusExamples/HelloWorld/par/HelloWorld.par Error: Executable /home/thejas/Cactus/exe/cactus_sim for configuration sim does not exist or is not readable Aborting Simfactory. previously I used the 2022 version and did the tov code, and got the output. I am now trying to do the multipatch wave equation.

Code champions for SpacetimeX thorns in ET_2023_11 release
by Cupp, Samuel D. 11 Aug '23

11 Aug '23

Hello all, Along with the proposed addition of the new CarpetX driver is a collection of other thorns reproducing features available in Carpet. Some of these are housed in the SpacetimeX arrangement, which is proposed for inclusion alongside CarpetX. However, I am not aware of who is 'championing' the individual thorns. Normally, this is one of the authors of the thorn who responds to any questions from reviewers, makes requested changes/additions, etc. Currently, I do not have anyone who is responsible for these thorns, at least in an official capacity. Can someone who contributed to writing these thorns please contact me in regard to who is serving as the 'code champion'? If no one is willing to take responsibility for them, they will not be included in the release. Samuel Cupp Postdoctoral Researcher Department of Physics University of Idaho
