Star disappear from grid
by Lorenzo Cipriani 19 Jan '24

19 Jan '24

Dear all, my name is Lorenzo Cipriani, PhD student at the University of L'Aquila. My goal is to simulate a BNS merger using initial data computed from Lorene and evolved according to the parameter file I have attached. Cactus reads the initial data correctly, as you can see in the image "rhoxy_initial.png" but, immediately after, the stars practically disappear from the grid, perfectly cut away (see image "rhoxy_it4.png"). Does anybody have a hint on what might be happening? I have never encountered a behavior like this. Thank you for your assistance, best regards, Lorenzo

Status of support for multiple floating point precisions in Carpet?
by Erik Keoni Wessel 18 Jan '24

18 Jan '24

Hi, I'm currently working on a thorn development project where it would be helpful to be able to have a mix of single-precision grid functions and double-precision grid functions (a very unusual need, I know). When I had my thorn allocate a grid function of type CCTK_REAL4, I got a message upon running my configurations that I needed to enable support for this type in Carpet. After reading through the Carpet documentation and then digging deep into the source code for CarpetLib, I discovered that there seem to be flags to compile Carpet with support for different types. I passed -DCARPET_ALL_REAL in as part of CPPFLAGS in my optionlist, but attempting to compile with other real types leads to compile-time errors about undefined functions: apparently headers for prolongation functions for all the types are generated, but somehow the corresponding definitions aren't being be linked correctly. I'm not sure what is going wrong, but I am also unable to find any examples of how support for other types is supposed to be enabled, so I am unsure if I am doing this right. So my question is: what is the status of support for grid functions of types besides CCTK_REAL8 in Carpet? Does this feature work, and if so, how can I enable support for all Cactus-supported real types in Carpet? Cheers, — Erik Wessel Department of Physics University of Arizona

It looks like the machine you are on does not allow you to use curl to download. Maybe checkout Cactus on your laptop and scp it to your machine? --Steve On 12/15/2023 12:16 PM, BRINGEN BUKAR wrote: > In an attempt to install the ET this error keep occurring can someone > help me out.

request for assistance

Dear Einstein Toolkit developers, My name is Liu and I am a student from Nagoya University. I am now learning to use ET to do some simulations. This time I am trying to reproduce this: https://einsteintoolkit.org/gallery/bns/index.html which is a simulation of binary neutron stars. During execution, I noticed this segmentation fault here when creating the simulation directory structure. (The screenshot file is attached to this email) This seems to be caused by a mismatch in memory settings. I've tried many debugging methods, but it still doesn't work. Could you please help me identify the issue? I am using Ubuntu 22.04.3 and I have already built the Einstein Toolkit and run a sample simulation successfully. Thank you very much for your sincerest help. Best regards, Liu Xiang

ET_2023_11 "Lise Meisner" Einstein Toolkit Release Announcement
by Cupp, Samuel D. 14 Dec '23

14 Dec '23

Release Announcement Click here to read the announcement in HTML (with hyperlinks): https://einsteintoolkit.org/about/releases/ET_2023_11_announcement.html We are pleased to announce the twenty-seventh release (code name "Lise Meitner") of the Einstein Toolkit, an open-source, community-developed software infrastructure for relativistic astrophysics. The major changes in this release include: Several new arrangements and thorns have been added: * CarpetX arrangement for the new AMReX-based mesh driver and supporting thorns * GRHayLib for access to the General Relativistic Hydrodynamics Library (GRHayL) * GRHayLID for simple GR(M)HD initial data using GRHayLib (e.g. Balsara tests, isotropic gas) * GRHayLHD for GRHD evolution using GRHayL (equivalent to IllinoisGRMHD with no magnetic fields) * GRHayLIDX for CarpetX version of GRHayLID; this thorn currently runs on the host, not the gpu * GRHayLHDX for CarpetX version of GRHayLHD; this thorn currently runs on the host, not the gpu * DNSdata for importing SGRID initial data New capabilities for existing codes: * Seed_Magnetic_Fields has been updated to support both TOV and BNS magnetic fields; explicit IllinoisGRMHD scheduling dependency removed to support broader usage; some parameter options are deprecated and will be removed in the next release In addition, bug fixes accumulated since the previous release in May 2023 have been included. The Einstein Toolkit is a collection of software components and tools for simulating and analyzing general relativistic astrophysical systems that builds on numerous software efforts in the numerical relativity community, including code to compute initial data parameters, the spacetime evolution codes Baikal, lean_public, and McLachlan, analysis codes to compute horizon characteristics and gravitational waves, the Carpet AMR infrastructure, and the relativistic (magneto)hydrodynamics codes GRHayLHD, GRHayLHDX, GRHydro, and IllinoisGRMHD. Data analysis and post-processing is handled by the kuibit library. The Einstein Toolkit also contains a 1D self-force code. For parts of the toolkit, the Cactus Framework is used as the underlying computational infrastructure, providing large-scale parallelization, general computational components, and a model for collaborative, portable code development. The Einstein Toolkit uses a distributed software model, and its different modules are developed, distributed, and supported either by the core team of Einstein Toolkit Maintainers or by individual groups. Where modules are provided by external groups, the Einstein Toolkit Maintainers provide quality control for modules for inclusion in the toolkit and help coordinate support. The Einstein Toolkit Maintainers currently involve staff and faculty from five different institutions and host weekly meetings that are open for anyone to join. Guiding principles for the design and implementation of the toolkit include: open, community-driven software development; well thought-out and stable interfaces; separation of physics software from computational science infrastructure; provision of complete working production code; training and education for a new generation of researchers. For more information about using or contributing to the Einstein Toolkit, or to join the Einstein Toolkit Consortium, please visit our web pages at http://einsteintoolkit.org, or contact the users mailing list users(a)einsteintoolkit.org. The Einstein Toolkit is primarily supported by NSF 2004157/2004044/2004311/2004879/2003893/2114582/2227105 (Enabling fundamental research in the era of multi-messenger astrophysics). The Einstein Toolkit contains about 400 regression test cases. On a large portion of the tested machines, almost all of these tests pass, using both MPI and OpenMP parallelization. Deprecated functionality * Seed_Magnetic_Fields: to support the changes, parameter options were renamed; the old options are deprecated and will be removed in the next release * Seed_Magnetic_Fields_BNS is slated to be removed in the next release, as its features have been merged into Seed_Magnetic_Fields Contributors Among the many contributors to the Einstein Toolkit and to this release in particular, important contributions to new components were made by the following authors: * Federico G. Lopez Armengol * Steven R. Brandt * Michail Chabanov * Cheng-Hsin Cheng * Samuel Cupp * Alexandru Dima * Jake Doherty * Lorenzo Ennoggi * Zachariah Etienne * Roland Haas * Terrence Pierre Jacques * Liwei Ji * Jay Kalinani * Philipp Moesta * Michal Pirog * Lucas Timotheo Sanches * Erik Schnetter * Swapnil Shankar * Wolfgang Tichy * Leonardo Werneck How to upgrade from Schwarzschild Release (ET_2023_05) To upgrade from the previous release, use GetComponents with the new thornlist to check out the new version. See the Download page (http://einsteintoolkit.org/download.html) on the Einstein Toolkit website for download instructions. The SelfForce-1D code uses a single git repository; thus, using git pull; git checkout ET_2023_11 will update the code. To install Kuibit, do the following: pip install --user -U kuibit==1.4.0 Machine notes Supported (tested) machines include: * Debian, Ubuntu, Fedora, Mint, OpenSUSE, and macOS X installations with dependencies installed as prescribed in the official installation instructions * Anvil * Deep Bayou * Delta * Expanse * Frontera * Sunrise Note for individual machines: * TACC machines: defs.local.ini needs to have `sourcebasedir = $WORK` and `basedir = $SCRATCH/simulations` configured for this machine. You need to determine $WORK and $SCRATCH by logging in to the machine. All repositories participating in this release carry a branch ET_2023_11 marking this release. These release branches will be updated if severe errors are found. The "Lise Meitner" Release Team on behalf of the Einstein Toolkit Consortium (2023-12-14) * Samuel Cupp * Steven R. Brandt * Peter Diener * Zachariah Etienne * Roland Haas * Liwei Ji * Deborah Ferguson * Gabriele Bozzola * Hyun Park December 14, 2023

question on GRHydro atmosphere mask
by Luciano Combi 14 Dec '23

14 Dec '23

Hello people. I've been using (a version of) GRHydro for a while and I was wondering if you know what motivated the use of an atmosphere mask. I understand that this is useful to set atmosphere states between mesh refinement levels, but I'd like to know if you've seen problems before just resetting locally to atmosphere. Thanks!!
