General Relativity CASprzak

GR_CASprzak is an extension of CASprzak whose goal is to automate many of the very long computations found in General Relativity/Tensor Calculus

Hello, and welcome to GR_CAS. When I was learning GR, I reached a point where I needed to calculate 256-term Christoffel Connections and Curvature Tensors and I didn't have a Mathematica license to do it the normal way. So instead I wrote this as an extension of a Computer Algebra System I am working on.

More information on the original CASprzak project can be found at: https://github.com/EasyKayzey/CASprzak.

Functionality

• Defining a Space or Geometry which you are working in.
  • Defined using a set of variables and a metric
• Calculating the Christoffel Connection
• Calculating the Riemann Curvature Tensor
• Calculating the Ricci Tensor
• Calculating the Ricci Scalar
• Calculating the Einstein Tensor
• Calculating the line element
• Calculating the volume element

Running

• Open this project in a decent Java IDE and write scripts in there
  • All code relating to this specific project can be found in src/GR
  • Look at the example code if you need help getting started
