Numerical Relativity -- Software to solve the Einstein field equations?

[dsaun777]

Hello,
Has anyone here used software to solve the Einstein field equations? If so, what software have you used, or what software do you recommend? Is it possible to use something like MATLAB to play around with the field equations?

You can do whatever you want, because you can do some spacetimes by hand, so why wouldn't you be able to code that into python, etc? You can tell someone is an older relativist if they bring up MAXIMA (along with perl, and lisp) haha.

That being said, if you want to do "real" numerical relativity, most people use in the field use https://einsteintoolkit.org/ to simulate things.

While looking for a paper in my bookmarks, I saw this: https://bhptoolkit.org/toolkit.html

It is a few years old, but should help.
