Acceleration of Unsteady Incompressible Flow Calculation Using Extrapolation Methods

Acceleration techniques are important in computational fluid dynamics as scientists and engineers hope to shorten the computational time. Although the multigrid method has been successful in achievement of quick convergence, this approach tends to show poor performance in parallel computing with the domain decomposition technique, especially when a small number of grid points are assigned to one processor. Another shortcoming of the multigrid method is complicated numerical procedures.
