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chose is outdated (try to find one that depends on VolumeIntegrals_GRMHD):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.
is used to find the center of masses of the neutron stars so their motion
can be tracked by the AMR grids.

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
