FTLE and trajectories of 2D integrable ABC flow

Description

Time series is generated using Runge-Kutta fourth order integration of 2D integrable ABC flow with A = B = 1.2 and C = 0. This time series serves as input for calculations of finite-time Lyapunov exponent (FTLE) and flow trajectories . The purpose is the identification of trajectories passing shear and strain barriers captured using FTLE.
