LCS MATLAB Kit Version 1.0 [.ZIP; 166 KB]
This MATLAB software package enables the user to input a time-series of velocity field data (e.g., DPIV measurements or CFD calculations) and compute the corresponding finite-time Lyapunov exponent (FTLE) fields, from which Lagrangian Coherent Structures (LCS) such as vortices and fluid transport barriers can be identified.
