This is from my own code but... could we add a comment here of the type

// We setup the inertial coordinates such that the element used for the evolution is centered on (6,0,0), and the jacobian matrix is the identity matrix


std::vector<Particles::MonteCarlo::Packet> packets{packet};
Particles::MonteCarlo::TemplatedLocalFunctions<2, 2> MonteCarloStruct;
// Getting N and CFL constant

I think "Getting N" is not needed here.

Add here a comment of the type
// Evolve a single Monte-Carlo packet along a geodesic of Kerr, and check that final position matches expectations.

@nilsdeppe @kidder I reviewed this, not sure what is the process for others to have a look (I'm not a maintainer so the tests won't run just based on my review)

@SamanthaRath Please look at the output of the test and fix as appropriate. For some of this, you'll want to compile your code in debug mode (some errors are just missing const and type conversions, but there is an array access out of bounds, which likely comes from some tensors being defined on the mesh without ghost zone when they need ghost zones)

Note that this replaces #6008

@kidder @nilsdeppe Could we run the test on this? Samantha uploaded changes that should handle the errors we got after rebasing against the new ghost zone code.
[Let me know if in the future I can just click 'run test' myself... it says maintainers only...]

Okay, I've never seen this message before

Alright, I'll ignore it then. I don't see why we shouldn't run the test...

variable types rectified with const
Also add ghost zones to MC evolution in Kerr test

@nilsdeppe @kidder Should be ready for someone else to look at it if desired.
