Forward FTLE computation from forward flowmap for Taylor Green flow
N_x = N_y = 60, N_t = 20 (0 to 1 sec)
N_x = N_y = 600, N_t = 20 (0 to 1 sec)
N_x = N_y = 60, N_t = 200 (0 to 1 sec)
Forward FTLE computation from inverting backward flowmap for Taylor Green flow
N_x = N_y = 60, N_t = 20 (0 to 1 sec)
Same case with location of unstructured data sample locations obtained from backward flowmap
