GRChombo: An adaptable numerical relativity code for fundamental physics
arXiv:2201.03458 · doi:10.21105/joss.03703
Abstract
GRChombo is an open-source code for performing Numerical Relativity time evolutions, built on top of the publicly available Chombo software for the solution of PDEs. Whilst GRChombo uses standard techniques in NR, it focusses on applications in theoretical physics where adaptability, both in terms of grid structure, and in terms of code modification, are key drivers.
