Data and MATLAB Code for "Nonlinear Dynamics of a Pulsatile-Flow Pipe with Velocity-Dependent Joint Impedance"

This record contains the MATLAB source code, model parameters, numerical data, and plotting scripts supporting the article “Nonlinear Dynamics of a Pulsatile-Flow Pipe with Velocity-Dependent Joint Impedance”. The files reproduce the constrained Gauss discrete-variational simulations, comparison calculations, convergence results, long-time response measures, and parameter studies reported in the manuscript. The package includes the numerical model, reference-solution procedures, post-processing scripts, and figure-generation routines required to reproduce the reported results.
