This code expands the original hermite code with post-newtonian terms.
From the AMUSE source directory run the following git command git submodule add [email protected]:amusecode/Hermite_GRX.git src/amuse/community/hermite_grx. This will add the code as a submodule such that the respective git structures do not interfere.
The code can then be compiled using make hermite_grx.code or all codes can be built together using python setup.py develop_build.
