Here u is the component of the velocity field in the x-direction and v the component in the y-direction. From In this paper we consider the time evolution of vortices simulated by the method of contour dynamics. Special attention is being paid this we can see that we are dealing with a Hamiltonian

Unconditionally stable higher order time-step integration algorithms are presented. The algorithms are based on the Newmark method with complex time steps. The numerical results at the (complex) sub-step locations are combined linearly to give higher order accurate results at the end of the time ste
