Abstract
The paper presents the development and investigation of an adaptivesmoothing (AS) procedure in conjunction with a full multigrid (FMG) — full approximation storage (FAS) method. The latter has been developed by the authors [1] for solving the incompressible NavierStokes equations, in conjunction with the artificialcompressibility method and a characteristicbased discretisation scheme, and forms here the basis for investigating the AS approach. The principle of adaptivesmoothing is to exploit the nonuniform convergence behaviour of the numerical solution during the iterations in order to reduce the size of the computational domain and, thus, reduce the total computing time. The results show that significant acceleration of the multigrid flow computations can be achieved by using adaptivesmoothing.
