Hi Ian,
As far as I know this wors fine. I have used it in EHFinder to evolve the generators of the horizon, where the coordinates are stored as 1-d grid arrays (like xg and its rhs dxg). However, I haven't run that code in a while, so I can't guarantee that it still works. I'm also using it in a thorn to integrate geodesics in Schwarzschild (for the self-force project). This thorn does work currently but is not yet in the EinsteinToolkit. If you want to take a look at it, just let me know.
Cheers,
Peter

Hi, What is the current situation with evolving grid arrays with MoL? Over the past 7 years, this topic has come up repeatedly on the mailing lists, and some of the old information is probably out of date. Is there a way to do this without using any hacks, or are hacks still necessary?
Is there an example somewhere of how to do this, or does someone have an example they would be willing to share?
