Computational methods for solving coupled systems of partial differential equations can generally be divided into segregated and monolithic solvers. Monolithic solvers are often considered to be computationally expensive, and it is believed that their rewards are realized only in situations where segregated solvers have convergence problems due to the strong coupling. We give opposite empirical evidence by demonstrating that cost-effective monolithic solvers may be derived from using segregated solvers as preconditioners in the iterative solution of monolithic systems.
