GRworkbench: A Computational System Based on Differential Geometry
Susan M. Scott, B. J. K. Evans, Antony Searle, C. Searle · 2001
We have developed a new tool for numerical work in General Relativity: GRworkbench. While past tools have been ad hoc, GRworkbench closely follows the framework of Differential Geometry to provide a robust and general way of computing on analytically defined space-times. We discuss the relationship between Differential Geometry and C++ classes in GRworkbench, and demonstrate their utility. 1
