The design of time-integration methods for steady state problems is discussed in this chapter, including a variety of methods for accelerating convergence to a steady state. A variety of convergence acceleration techniques are discussed, including ways in which the time integration process itself may be optimized for steady state calculations. In this case, the accuracy of the time integration scheme is no longer a consideration. This enables the use of modified RK schemes of reduced computational complexity. Moreover, the schemes may be tailored to increase the allowable time step, thereby promoting more rapid convergence to a steady state. Moreover, they can be tailored to drive multigrid acceleration.
