A code to evolve the equations of hydrodynamics in curved spacetime (relativistic numerical hydrodynamics).

A modular manageable high-performance 3D tool for Numerical Relativity.

Package written in Maple for calculating tensor components in General Relativity and performing some abstract tensor manipulation; suitable for calculations in general relativity and for quantum field theory in curved spacetime. Features brief description, download for Maple V and for Maple 6 or higher, and examples.

A Mathematica package for doing tensor calculations in differential geometry and general relativity.

An open framework for large numerical simulations in general relativity.

Provides a set of C++ classes to solve various problems arising in numerical relativity and other areas of computational astrophysics.

A computer algebra package for performing differential geometry calculations. Demonstrations of the package's applications to general relativity.

Software for modelling gravitational lens systems; created and maintained by Chuck Keeton at Rutgers University.

A free software package for manipulating tensors (abstract index notation) and other multi-component objects; highly suitable for calculations in general relativity and related theories such as supergravity. Documentation, course material, and possibilities for download.

Product information from Ad Infinitum AS about a package for use with the Mathematica software; allows interactive tensor calculations in spacetimes of arbitrary dimension.

A mesh refinement driver for the Cactus code; the primary application is the simulation of black hole spacetimes.
