</div>Dear Maitraya,<br>
<br>
since you have a spherically-symmetric spacetime, your problem is much<br>
simpler than what EHFinder was designed for, and in my opinion it isn't<br>
worth the effort of turning your data into 3+1 and importing it in Cactus.<br>
<br>
My suggestion is that you take a look, e.g., at section 7.2 of this book:<br>
<br>
<a href="https://books.google.it/books?id=dxU1OEinvRUC" rel="noreferrer" target="_blank">https://books.google.it/books?<wbr>id=dxU1OEinvRUC</a><br>
<br>
You'll see than in spherical symmetry the problem greatly simplifies,<br>
and can be solved with a few lines of code.<br>
<br>
I hope this helps,<br>
Eloisa<br>
