It enables users to input a time-series

of 2-D velocity field data (e.g., DPIV measurements or CFD calculations) and

compute the corresponding finite-time Lyapunov exponent (FTLE) fields, which

Lagrangian Coherent Structures (LCS) suchas vortices and fluid transport barriers

can be identified.- It enables users to input a time-series
