... frequency components do not significantly interfere with each other because of vety different time scales. They are subsequently assessed separately in the framework of this approximation. The low frequency component is usually obtained by time domain simulations which solve at each time step a vectorial...

.... If the governing equations (2) were linear then Equation (5) could be used to simply step through time to obtain the solution. However, the nonlinearities present in Equation (2) mean that an itera- tive procedure must be adopted at each time step in order to achieve a solution of known accuracy. The solution pro...

The method is based on treating the problem as a transient one with known initial conditions, with the flow development obtained by a time-stepping method involving the application of Green's theorem at each time step.
