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:
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,
