SteadyStateTool: Fast computation of Steady-State response of multi-degree of freedom nonlinear mechanical systems
Latest release:
This program computes the steady-state response (SSR) of multi-degree-of-freedom nonlinear mechanical systems under multi-frequency forcing using the integral equations approach propoposed in the following article:
S. Jain, T. Breunung, G. Haller, Fast Computation of Steady-State Response for Nonlinear Vibrations of High-Degree-of-Freedom Systems, Nonlinear Dyn (2019) 97: 313. https://doi.org/10.1007/s11071-019-04971-1
Apart from steady-state response prediction in the full system, this program also allows for mode selection and model reduction using the selected modes according to the theory proposed in following article:

Upon downloading and extracting the files, please set the CURRENT FOLDER in MATLAB by browsing to the folder containing startup.m file. Thereafter, please run the startup.m file or simple type "startup" in the MATLAB COMMAND WINDOW. You are now ready to play with examples and create new ones!
We have tested this program with MATLAB version 2018a,2018b,2019a,2019b.
Please report any issues to Shohit Jain (shjain at ethz dot ch)
