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

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.

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

An open framework for large numerical simulations in general relativity.

A Mathematica package for doing tensor calculations in differential geometry and general 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 code to evolve the equations of hydrodynamics in curved spacetime (relativistic numerical hydrodynamics).
