[Users] Black hole data for EHFinder

[Maitraya Bhattacharyya]

Dear Eloisa,

My ultimate goal is to look at more general data, hence I want to start
knowing how to use EHFinder.

Any type of black hole simulation data and instructions on how to run
EHFinder is highly appreciated.

Maitraya.

Dear Maitraya,

since you have a spherically-symmetric spacetime, your problem is much
simpler than what EHFinder was designed for, and in my opinion it isn't
worth the effort of turning your data into 3+1 and importing it in Cactus.

My suggestion is that you take a look, e.g., at section 7.2 of this book:

https://books.google.it/books?id=dxU1OEinvRUC

You'll see than in spherical symmetry the problem greatly simplifies,
and can be solved with a few lines of code.

I hope this helps,
Eloisa
