“…A third direction of improvement which needs to be pursued is the integration of multigrid solution strategies with procedures for automatic grid refinement. Results which have already been obtained in two dimensional calculations clearly show the potential advantages of such an approach, which could be the key to better resolution of both shock waves and boundary layers [49,50].…”

“…The first step of the multiple grid procedure is to transport the fine grid residuals to the coarse grid. The first-order change at the center of a cell A is [10,27] 1 The contributions to the change at node 1 from the cells with centers at B,C,...,H are computed in a similar way. After the changes are computed, boundarj'^ conditions in the near field are applied.…”

“…(1)- (3), (9), and (10) are solved using a Lax-Wendroff control-volume, time-marching scheme as developed by Ni 17 , Dannenhoffer 18 , and Davis 19,20 . Numerical solution of unsteady flows is performed with a dual time-step procedure 21 , allowing for use of multiple-grid and local time-stepping convergence acceleration.…”
