GRTensorIII is a package for the Maple computer algebra system to perform component and basis calculations for General Relativity. It defines a large number of standard tensor, basis and NP objects. It also allows new objects to be defined and calculated. It is used to calculate objects of interest in specific spacetimes. It allows the entry of new spacetimes in tensor or basis form interactively.
GRTensorIII requires Maple 18 or later from http://www.maplesoft.com/
GRTensorIII is intended to work on all platforms (PC, Mac or Linux). It has been validated on Mac (ElCap/Sierra), Linux (Ubuntu 14.04) using Maple 2015 and 2016. Please report any compatibility issues to the support email grtensor3@gmail.com.
