Gravitas

Forked from https://github.com/JonathanGorard/Gravitas

Gravitas is a Wolfram Language package for symbolic and numerical computations in general relativity, with a focus on discrete and continuum formulations of gravitational physics.

Features

• Symbolic manipulation of tensors and metrics
• Computation of curvature tensors (Riemann, Ricci, Einstein, Bach, etc.)
• ADM decomposition and stress-energy analysis
• Discrete hypersurface and geodesic calculations
• Tools for both continuum and discrete approaches to gravity
