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

Click For Summary
SUMMARY

This discussion centers on software solutions for solving the Einstein field equations in the context of numerical relativity. The Einstein Toolkit, available at einsteintoolkit.org, is the most widely used software for simulations in this field. Additionally, the BHPT Toolkit, found at bhptoolkit.org, is mentioned as a useful resource, despite being a few years old. The conversation also touches on the potential of using MATLAB and Python for custom implementations of the field equations.

PREREQUISITES
  • Understanding of the Einstein field equations
  • Familiarity with numerical relativity concepts
  • Basic knowledge of programming in Python or MATLAB
  • Awareness of existing numerical relativity software like the Einstein Toolkit
NEXT STEPS
  • Explore the Einstein Toolkit for practical applications in numerical relativity
  • Investigate the BHPT Toolkit for additional resources and methodologies
  • Learn how to implement the Einstein field equations in Python
  • Research the capabilities of MATLAB for simulating spacetimes
USEFUL FOR

Researchers in theoretical physics, astrophysicists, and software developers interested in numerical relativity and the simulation of gravitational phenomena.

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.

Thread 'EPR revisited'

In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$ \frac{1}{\sqrt{2}}(|0>_A|1>_B+|1>_A|0>_B) $$ At point A, a measurement is made. The state then collapses to $$ |a>_A|b>_B, \{a,b\}=\{0,1\} $$ We assume that A has the state ##|a>_A## and B has ##|b>_B## simultaneously, i.e., when their synchronized clocks both read time T However, in other inertial frames, due to the relativity of simultaneity, the moment when B has ##|b>_B##...
