Using Cadabra for tensor computations in General Relativity. Brewin, L. *arXiv:1912.08839 [gr-qc]*, December, 2019. arXiv: 1912.08839 Repository: https://github.com/leo-brewin/cadabra-tutorialPaper abstract bibtex Cadabra is an open access program ideally suited to complex tensor commutations in General Relativity. Tensor expressions are written in LaTeX while an enhanced version of Python is used to control the computations. This tutorial assumes no prior knowledge of Cadabra. It consists of a series of examples covering a range of topics from basic syntax such as declarations, functions, program control, component computations, input and output through to complete computations including a derivation of two of the BSSN equations from the ADM equations. Numerous exercises are included along with complete solutions. All of the source code for the examples, exercises and solutions are available on GitHub.
