My version of GRChombo, primarily adding mass variations

Katy's GRChombo

This is Katy's working version of the GRChombo code (as in, "I'm working on it", not "the code is working" :-).

Use at your own risk! It is likely that many things will be broken and may disappear without warning.

GRChombo

GRChombo is a new open-source code for numerical general relativity simulations. It is developed and maintained by a collaboration of numerical relativists with a wide range of research interests, from early universe cosmology to astrophysics and mathematical general relativity, and has been used in many papers since its first release in 2015.

GRChombo is written entirely in C++14, using hybrid MPI/OpenMP parallelism and vector intrinsics to achieve good performance on the latest architectures. Furthermore, it makes use of the Chombo library for adaptive mesh refinement to allow automatic increasing and decreasing of the grid resolution in regions of arbitrary shape and topology.

Please visit www.grchombo.org for the full list of developers and their institutions, a list of publications using GRChombo, and some videos.

Getting started

Detailed installation instructions and usage examples are available in our wiki.

IMPORTANT: Updating examples for diagnostic variables

If you wish to merge diagnostic variables changes in this branch into an older branch, you will need to update old examples. Please consult this wiki page.
