.... 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...
