Routines for the computations of periodic orbits using Melnikov and Newton method in a piecewise-smooth system (the rocking block with restitution coefficient)
Collection of C and bash routines for the computation of periodic orbits via Melnikov method in a piecewise-smooth system This software is the one used to compute the numerical results presented in The Melnikov method and subharmonic orbits in a piecewise-smooth system .
List of files, routines and their goals
- system.dat contains system parameters: n m y0 t0 delta rho omega, where
- nT is the period of the desired periodic orbit
- 2*m the number of impacts
- y0 is the initial seed for the Newton method, such that (0,y0) is the initial condition for an nT period orbit of the unperturbed system
- t0 is the zero of the modified Melnikov function
- delta is perturbation parameter
- rho is the ratio between the forcing and the restitution coefficient
- omega is the frequency of the forcing
