Doing physics with GRChombo

These sections assume that you have successfully followed the compilation instructions in Getting started. You may wish to refer to Capabilities to get an idea of what tools are available in the code.

Here we aim to give a broad outline of the structure of the code and our design philosophy for new examples. If you need further guidance you should contact us, and we will do our best to help. (However, note that the informal GRChombo motto is "if you want it, you build it".)

Please note our License and Citation guidance.
