Simulation code for Bravetti, Seri, Zadra: New directions for contact integrators

The notebooks contain the code to generate the pictures used in the paper, these can additionally be found in the images/ folder. The integators folder contains the implementations of all the algorithms tested. The notebooks can be run remotely via binder, clocking on the badge above, or locally by using jupyter, a recent version of python, numpy and matplotlib is required (see requirements.txt for a compatible set of dependencies).

The available notebooks, containing the code to generate the pictures in the paper, are:

• The Time-Perturbed Kepler Problem.ipynb;

• Contact Oscillator.ipynb
