Hi, I had a doubt about this graph, Why do we have a 'Mass of the sun' parameter in the x-axis, What is the logic behind it? Warm Regards

Present: Roland, Leo, Zach, Peter, Sam, Yosef ET release ========== * reviewers needed for AsterX. Roland to poke Bruno and EU people. * Yosef is reviewer for SpaceTimeX, still not specific list of thorns to include. Sam will ask for final list on mailing list. Thorns not volunteered and champions stepping forward will be dropped from the release. * Reviewer found for SGRID * need testsuite runners and gallery runners ** Steve would do BBH gallery example again ** please suggest possible helpers * Sam created / reactivated tickets for release ET summer school ================ * recordings are still being processed (Yosef is the sole editor right now) Unanswered emails ================= * http://lists.einsteintoolkit.org/pipermail/users/2023-August/009021.html Roland will try and follow up, but is not sure what is going on. Might be simfactory failure or might be in simfactory or some homebrew / machports / user editing issue * http://lists.einsteintoolkit.org/pipermail/users/2023-August/009020.html Roland had been in contact. Not sure what is going on, might be an issue with simfactory setting up new segments instead of creating a new simulation. Tickets ======= * https://bitbucket.org/einsteintoolkit/tickets/issues/2706/update-default-tw… Zach will coordinate with Steve about TP paramters * pull request https://bitbucket.org/cactuscode/cactusnumerical/pull-requests/13 Peter will take a look to see what / if needs to be done Tickets for review ================== * no updates for most of them * https://bitbucket.org/einsteintoolkit/tickets/issues/963/improve-mclachlan-… Peter will look into the after Zach's paper with improved methods is out * https://bitbucket.org/einsteintoolkit/tickets/issues/2653/carpet-presync-tr… issue is triggered if there are no b/c to apply, then PreSync will try and SYNC + bc every time. There probably is some better fix for this. Some fine tuning of warnings / errors may be required. chair next week: Peter minutes taker next week: Sam Yours, Roland -- My email is as private as my paper mail.

Adding extra object file at linking stage
by Most, Elias R. 07 Aug '23

Hi, I have an extra object file “.o” that was compiled externally, but needs to be linked in during the linking process. Is there a standard way to include this within the build process? Thank you, Elias

rel. fluids in the Toolkit
by Bill Gabella 03 Aug '23

03 Aug '23

Okay this is a general question...how are relativistic fluids handled in the Einstein Toolkit? Yup, overly broad I know. So more specifically, o Are there good reviews, references, or lectures that describe how we currently handle fluids? For the different models? o I gather we have several models/codes: GRHydro and IllinoisGRMHD, so resources on those would be much appreciated. o And initial data readers exist for the LORENE (1 and 2?) and for the FUKA data...resources there might be helpful too. I am hoping for some introductory information (a review would be great) on all our fluid codes, as well as other codes used in other numerical relativity systems. Some context: I rub elbows with mathematicians who work in relativisitic fluids (ideal, viscous, etc) and they do not believe that any codes out there can do fluids "correctly." I am trying to understand what we do in the Toolkit and also what they expect "correctly" (my language) to be. thanks for any help, bill e.g.

Attendees: Samuel Cupp, Roland Haas, Peter Diener, Steven Brandt, Zach Etienne, Keith Dow, Yosef Zlochower Summer School recap: We need more disk space Encourage each tutorial speaker to test notebooks Need to report number of both in person and online participants. ET 2023_11 release: Need volunteer reviewers (see list at https://docs.einsteintoolkit.org/et-docs/Meeting_agenda 2023-08-03 minutes) Need more CarpetX documentation Need more CarpetX testsuites May need multiple reviewers for spacetimeX (Yosef volunteers). Who are the champions ? Potential issues of duplicated thorns/code when Carpet and CarpetX are both in the toolkit. Reviewers needed for GRHayL thorns (Peter volunteers) Reviewers needed for AsterX Chair Next week: Samuel Cupp Minute taker:
