Simulation domain volume and reduction weight sum differ
by Jakob Hansen 25 Sep '12

25 Sep '12

Hi, Using mercurial, I get this warning during simulations : INFO (CarpetReduce): Simulation domain volume: 170368000 INFO (CarpetReduce): Reduction weight sum: 170367999.880642 WARNING level 1 in thorn CarpetReduce processor 0 host tachyon2974 (line 120 of /home01/r632kgw/jakob/CactusP/arrangements/Carpet/CarpetReduce/src/mask_test.c): -> Simulation domain volume and reduction weight sum differ Simulations seem to run okay though. What is causing this warning and is it serious or can I just ignore it? Cheers, Jakob

Hi, Are there objections to change the default of TmunuBase::support_old_CalcTmunu_mechanism from "yes" to "no"? Frank

two-punctures documentation
by Comer Duncan 28 Aug '12

28 Aug '12

Hi, I can not seem to find a non-vacuous version of the Einstein Toolkit documentation for TwoPunctures. On my local machine, I can generate a latex file TwoPunctures.tex but looking it over shows that the various sections fo the documentation have not been fleshed. Am I seeing something because my build (or attempted build) of the ThornGuilde.pdf has failed? I can not get the make of ThornGuide.pdf to complete on my machine (mac osx Mountain Lion with latex fully flavored since I upgraded to Mountain Lion). Can you guys please point me to somewhere which has the fully built documentation.pdf? I am using Lovelace since July. Thanks much. Comer

meeting minutes
by Roland Haas 27 Aug '12

27 Aug '12

Present were: Erik, Peter, Roland, Frank, Steve, Ian, Christian Ott, ELoisa, Yosef, Bruno, Tanja ET fall workshop: * dates are now fixes to week of Oct 22nd, from Mo (22nd) at noon to Fri (26th) at noon * hotel information available on the wiki page https://docs.einsteintoolkit.org/et-docs/ET_Workshop_Fall_2012 * physics topics: - MHD related: vector potential, resistive MHD, force-free MHD (on its own, coupled to ideal mhd, as limiting case in Con2Prim, ...) - radiative transport: possible enhance Caltech leakage code for general geometries (for NSNS mergers), however: was explicitly taken out of proposal due to funding cut - ID solver for complex EOS: Frank will contact Nick Stergioulas about making (a version of) RNSID public, with the ET adding complex EOS support using EOS_Omni (note: there apparently already is support for complex EOS using a private interface) - cosmology: Eloisa and Erik interested, Eloisa willing to give a 1hr presentation to get things started - MP: -- needs final ok from developers, details of publication need to be discussed -- Is well tested in vacuum and supported by Kranc. Hydro support is being used for publication work and should also work, but is less well tested -- MHD part is essentially untested and not complete (but simple to add). -- Erik agreed to give a presentation to teach how to use it and to point out the secrets to make things work (or fail). -- unlikely to be included in next release but possibly shortly after, to be discussed at workshop * collect registration fee to pay for catering (Yosef will ask Josh), should not be more than USD ~50 MHD: * paper is due since the grant will run out soon * will mention characteristic speed issue in paper * Bondi infall has problems with interpolation from 1d to 3d * will coordinate via email and have authors commit to tasks for this week Misc: * will have a call on labour day Yours, Roland

Einstein Toolkit Meeting

Hi Please consider joining the weekly Einstein Toolkit phone call at 10 am US central time on Mondays. As usual, you can find instructions how to join on the following web site: http://einsteintoolkit.org/community/support/ I short: the number is (+1) 225-578-4942 or (+1) 866-573-0359 and the conference id is 118682#. We will discuss topics for the fall ET developer workshop [1], which will take place from Oct 22nd to Oct 26th at RIT. In particular, more physics related topics are called for (rather than CS-oriented, as we have enough on the table there already). Activity last week includes 11 active and still open bugs and three closed issues: - For the issue of compiled documentation it was decided to keep it for the sake of easy availability to users. - Reductions within SphericalSurface are now not attempted unless auto_res[n] is set. - Error message improvements in Carpet 10 Tickets are waiting for review at the moment [2]. Please see if you can help. Frank Loeffler [1] https://docs.einsteintoolkit.org/et-docs/ET_Workshop_Fall_2012 [2] https://trac.einsteintoolkit.org/query?status=review&group=component&col=id…
