After the stopping criteria have been met, you may decide that the simulation is complete. In this case, the simulation can be saved and the required post-processing can commence. However, it is equally likely that you will want to change the stopping criteria and continue running. For instance, if a simple stopping criterion such as number of iterations was used, the iterations will stop before acceptable convergence has been reached. In this case, the stopping criteria can be changed and the solution continued by running again.
