binary neutron stars with gas surrounding
by 黃世杰 07 Aug '18

07 Aug '18

If I want modify the parameters file (code) --"NsNsToHMNS.par" of the binary neutron stars in the* "gallery example"* to simulate the non vacuum binary neutron stars (and the gas surrounding could be in different density and velocity distribution, should I add some thorns into the parameters file(NsNsToHMNS.par )? if yes, what should I add? )how could I do ? thank you~~ Best, Jie

meeting minutes for 2018-08-06
by Roland Haas 06 Aug '18

06 Aug '18

Present: Roland, Sam, Steve, Yosef, Bhavesh, Peter, Gary W Pearson, Bill ET release: * dates conflict with ET EU meeting * will have release just after the meeting so that the tutorials can still use the old release * will start testing testsuites. Roland on clusters and OSX, Steve on Linux. Gallery examples: * BBH: Sam has job that ran on SuperMike will look at it today * TOV: works * Scalar field: works * BNS: Peter ran the example with old code and that matches the gallery, so there is indeed a code change that caused this. Significant differences are present in central density and amplitudes. Now we have to understand what causes the differences by trying to compare testsuite differences between the two versions. Reviews: * Peter looked at Proca and has not seen anything terrible yet * Steve will look at WVU_Diagnostics * Lean still needs a reviewer * no progress on GiRaFFE Education working group: * please review https://docs.einsteintoolkit.org/et-docs/images/e/ed/EinsteinToolkit_Educat… for compliance with https://docs.einsteintoolkit.org/et-docs/ET_Working_Group_Policies_and_Proc… Read-write-based scheduler: * Sam checked runtimes using PreSync vs. the current ET code and finds significant speedup of about 20% in all the tests which is accounted for in the SYNC calls, indicating a lot of oversynchronization. These tests include ML_BSSN. ET wiki: * close to having a new version of the wiki * will have its own local logins and no longer rely on the CCT LDAP * container for wiki is well under way * hopeful to be able to let everybody edit the wiki by the end of this week Yours, Roland -- My email is as private as my paper mail.

non vaccum binary neutron star

If I want to stimulate the binary neutron stars in the gas to see if there are some special phenomenon, such like the collision of two accretion disks, or when a wind blows in the process, what will happen, what should I do? how to modify the parameter file? Please give me some guides. best, Jie
