ABSTRACT
Trajectory based approaches have proved invaluable in most areas of dynamics. In chemistry, trajectory based classical molecular dynamics has made it possible to study the dynamics of up to 103-104 atoms, and its success in this field is well documented. In fluid dynamics, Lagrangian trajectory based methods have also proved popular and are the method of choice for many fields in the fluid dynamics community. Trajectory based approaches have the advantages that they provide an intuitive insight into a dynamical process and, as witnessed in classical molecular dynamics, trajectory based approaches can be very computationally efficient.
