Conclusions<br />
1 We can compute evolving forward and backward time FTLE fields during direct<br />
numerical simulation <strong>of</strong> unsteady and turbulent flow<br />
2 The integration allows for high resolution FTLE computations, using the native<br />
space and time resolution <strong>of</strong> the simulation<br />
3 We have tested the implementation for 2D and 3D flows with both fixed & moving<br />
boundaries as well as complex configurations<br />
4 The FTLE computations contribute to 26% or less <strong>of</strong> the total simulation time, and<br />
require only moderate amounts <strong>of</strong> RAM/disk space.<br />
Future Work<br />
1 Precise extraction <strong>of</strong> LCS from developing theory<br />
2 Extension to inertial particles<br />
3 Simulations <strong>of</strong> FTLE based control<br />
