Is there a patch?

Data from the simulation GW150914
by Максим Мисюра 18 Apr '24

18 Apr '24

I am Misyura Maxim and I am conducting research into how strong gravitational waves interact with matter. Am I correct to assume that I can obtain the full data from the simulation GW150914. In particular, I am interested in the values provided by ADMBASE, otherwise, it would be necessary for me to download all the available data. Sincerely yours, Misyura Maxim, PhD student of Saint-Petersburg State University

Meeting minutes for 2024-04-18
by Leo Rosa Werneck 18 Apr '24

18 Apr '24

Hi all, Here are the minutes for today’s ET call. Chair: Zach Etienne Minutes: Leo Werneck Present: Roland Haas, Leo Werneck, Peter Diener, Sam Cupp, Zach Etienne Johnny Tsao, Lucas Sanches, Steve Brandt * NA ET School/Workshop @ LSU - June 3-7 (https://www.cct.lsu.edu/Einsteintoolkitworkshop2024). - Checking participant support cost availability for both domestic and international participants. - Preliminary schedule in progress, but still missing speakers. - There will be an excursion to LIGO, scheduled for the afternoon of June 5. - Leo requested a hands-on tutorial on how to set up and run containers in HPC systems, for reproducibility and portability. * ET Release - Review deadline: tomorrow! - Baikal/GRHayLHD: Terrence is actively reviewing. - IllinoisGRMHD: haven't heard from Lorenzo yet. * Online ET Tutorial - Requested by a research group from Denmark who contributed to the toolkit. - The Amsterdam workshop can be useful, if it happens. - Roland looking for lecturers/tutorial givers. - Roland will know more details by next week. - For those in the West coast: keep in mind the time zone difference. * Mailing List - Misyura Maxim is interested in obtaining the data for GW150914. Message will be forward to authors, as Zenodo doesn't contain all the data. - A student from Nanjing Normal University inquired about LORENE. Zach will forward the message to Josh. * Open Tickets - #2760: simfactory had warnings with Python 3.12. Steve and Roland worked on it, and asked Zach to review. Most of the fixes involved strings used for regex into raw strings. - #2791: use apptainer rather than Docker for documentation. - #963: improve McLachlan accuracy; Zach and Peter will meet about it. * Tickets ready for review - #2760: see above. - #963: see above. - #2786: Multipole support in CarpetX, stalled after discussion.

some questions regarding the use of LORENE to generate initial data for the merger of binary neutron stars.
by 巾非凡文 18 Apr '24

18 Apr '24

Professor, hello. I am an undergraduate student from Nanjing Normal University. My research topic is related to the merger of binary neutron stars. However, I have encountered some difficulties in generating initial data with LORENE, and I hope to receive your assistance. Thank you very much. I have downloaded the LORENE library in the Fedora virtual machine environment and selected some test examples from the website at https://ccrgpages.rit.edu/~jfaber/BNSID/. Here are my specific operations: First, I replaced the file "binaire_orbite.C" in the Codes folder with the one I downloaded in the LORENE folder, and replaced the file "coal_seq_massscan.C" with the "coal.c" file in the "/Lorene/Codes/Bin_star" directory of the LORENE folder. Next, I selected the example in the "Data/AP4/AP4_1.8_1.4" folder on the website for simulation calculations. Among them, I copied the six files, "par_eos1.d", "par_eos2.d", "par_grid1.d", "par_grid2.d", "par_init.d", and "parcoal_seq.d.40km", to the "/Lorene/Codes/Bin_star" directory of the LORENE folder. Subsequently, I ran the command in the terminal of that directory. The specific command I executed is as follows: make init_bin make coal make lit_bin ./init_bin ./coal However, during the execution process, I encountered the following assertion error: coal: /home/lhc/Lorene/C++/Include/tbl.h:282: double& Lorene::Tbl::set(int): Assertion `etat == ETATQCQ' failed. Aborted (core dumped) Next, I modified the line 282 in the file "/home/lhc/Lorene/C++/Include/tbl.h" from etat == ETATQCQ to true and attempted to run it again. This time, there was no assertion error reported.   After running for about an hour, I obtained the following files: However, the initial data file I obtained is different from the initial data files in the "Data/AP4/AP4_1.8_1.4" folder on the website https://ccrgpages.rit.edu/~jfaber/BNSID/. Specifically, the file I got is named "resu_4.000000e+01_2.080000e+00_1.550000e+00.d".   Do you know why this is the case? Is it due to my incorrect operation steps that led to this issue? 巾非凡文 shenfei2002(a)foxmail.com
