#2599: nsnstohmns cannot be reproduced using LORENE2

#2599: nsnstohmns cannot be reproduced using LORENE2 Reporter: Ken Hui Status: open Milestone: ET_2021_05 Version: ET_2021_05 Type: bug Priority: minor Component: Cactus Comment (by Roland Haas): Thanks for the update. The changes in solar mass and and gravitational constant I can understand $and expect$. Though how can MeV in Joule change? It’s essentially the electron charge which I would have expected to be very well known. I agree that the plots are not directly useful. The interesting bit would be that failure happens once the central density rises ie star start to interact. Another useful plot, since the grid structure is what fails would be a plot of the grid structure. Eg using the plot-bboxes tool in [https://bitbucket.org/eschnett/carpet/src/master/Carpet/src/util/plot-bboxe… It expects as input one of Carpet’s `carpet-grid-structure` files: ``` > gnuplot $ load "plot-bboxes" ``` then paste $since it reads from `/dev/tty`$ one of the sections from the grid structure file, eg: ``` iteration 0 maps 1 0 mglevels 1 0 0 reflevels 3 0 0 0 components 2 0 0 0 0 0 ([0,0,0]:[136,136,68]:[4,4,4]/[0,0,0]:[34,34,17]/[35,35,18]/22050) [[1,1,1],[1,1,0]] 0 0 0 1 1 ([0,0,72]:[136,136,136]:[4,4,4]/[0,0,18]:[34,34,34]/[35,35,17]/20825) [[1,1,0],[1,1,1]] 0 0 1 components 2 0 0 1 0 0 ([36,36,36]:[100,100,68]:[2,2,2]/[18,18,18]:[50,50,34]/[33,33,17]/18513) [[0,0,0],[0,0,0]] 0 0 1 1 1 ([36,36,70]:[100,100,100]:[2,2,2]/[18,18,35]:[50,50,50]/[33,33,16]/17424) [[0,0,0],[0,0,0]] 0 0 2 components 2 0 0 2 0 0 ([52,52,52]:[84,84,68]:[1,1,1]/[52,52,52]:[84,84,68]/[33,33,17]/18513) [[0,0,0],[0,0,0]] 0 0 2 1 1 ([52,52,69]:[84,84,84]:[1,1,1]/[52,52,69]:[84,84,84]/[33,33,16]/17424) [[0,0,0],[0,0,0]] ``` which should produce this plot: ![](https://bitbucket.org/repo/8zBLME5/images/1133471296-image.png) This may also be possible with a dedicated Cactus analysis package like SimulationTools or Kuibit or PyCactus/PostCactus listed on [https://docs.einsteintoolkit.org/et-docs/Analysis\_and\_post-processing](ht… . ‌ -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2599/nsnstohmns-cannot…

#2599: nsnstohmns cannot be reproduced using LORENE2 Reporter: Ken Hui Status: new Milestone: ET_2021_05 Version: ET_2021_05 Type: bug Priority: minor Component: Cactus Comment (by Roland Haas): The error you see is very late and really related to the grid structure $and really should never happen$. We had some instances of small changes in initial data changing results of the BNS gallery example at very late times $close to merger$, though never really in a production setup. This is discussed in ticket #2119 . It is very low resolution so some fragility is expected though this change is a bit unexpected. Can you check that the results up to the point of failure are “sane”? Can you provide a “diff” of the changes you made to `unites.h`, please? ‌ -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2599/nsnstohmns-cannot…
