A more efficient anisotropic mesh adaptation for the computation of Lagrangian coherent structures
Briffard T., Fortin A.
Département de mathématiques et de statistique, Université Laval

The computation of Lagrangian coherent structures is more and more used in fluid mechanics to determine subtle fluid flow structures. We present in this paper a new adaptive method for the efficient computation of Finite Time Lyapunov Exponent (FTLE) from which the coherent Lagrangian structures can be obtained. This new adaptive method considerably reduces the computational burden without any loss of accuracy on the FTLE field.
