Dear Chia-Hui, > Is there a thorn called VolumeIntegrals ?
No, there isn't, and this *might* be evidence that the parameter file you chose is outdated (try to find one that depends on VolumeIntegrals_GRMHD): the old "VolumeIntegrals" thorn was split into the VolumeIntegrals_GRMHD and VolumeIntegrals_vacuum thorns. The former can use IllinoisGRMHD gridfunctions and the latter can use McLachlan gridfunctions. VolumeIntegrals_GRMHD is used to find the center of masses of the neutron stars so their motion can be tracked by the AMR grids. > And I am curious about: what is the main difference between the parameter file (nsnstohmns.par) in the gallery example and nsns_test.par ? The nsns_test.par is designed to evolve the "Missing Link" case ( https://arxiv.org/abs/1101.4298), which is probably different than the gallery example. To run this case, you'll need to use the LORENE initial data file here (credit: Meudon group; you can find this case on the LORENE website -- https://lorene.obspm.fr/ -- as well, but you'll need to hunt for it): http://math.wvu.edu/~zetienne/resu.d -Zach * * * Zachariah Etienne Assistant Professor of Mathematics West Virginia University *https://math.wvu.edu/~zetienne/ <https://math.wvu.edu/~zetienne/>* https://blackholesathome.net On Tue, Jul 17, 2018 at 9:26 AM, 林家暉 <[email protected]> wrote: > Dear Zach, > > Sorry for late reply.
