Cactus Code Thorn WeylScal4 Author(s) : Tanja Bode Ian Hinder Roland Haas Erik Schnetter Maintainer(s): Cactus team Licence : LGPL -------------------------------------------------------------------------- 1. Purpose Calculate the Weyl Scalars for a given metric given the fiducial tetrad of Baker, Campanelli, and Lousto. PRD 65,044001 (2002) without the final null rotations. 2. Implementation The code is generated automatically with Mathematica. The Mathematica scripts are in the subdirectory "m", and the Makefile in there re-generates the code. This requires Mathematica and Kranc to be installed. The scripts look for a Kranc installation in the "m" directory, in the Cactus root directory and in $HOME as well as in the location where they find the kranc shell-script if it is in the $PATH. If your Kranc (or kranc) directory is in neither of these places, then you can set the environment variable KRANCPATH to the location of your Kranc installation. This thorn was generated using Kranc from http://github.com/ianhinder/Kranc
