Accelerated Multigrid Convergence and High-Reynolds Recirculating Flows
نویسندگان
چکیده
Techniques are developed for accelerating multigrid convergence in general, and for advection-diffusion and incompressible flow problems with small viscosity in particular. It is shown by analysis that the slowing down of convergence is due mainly to poor coarse-grid correction to certain error components, and means for dealing with this problem are suggested, analyzed, and tested by numerical experiments, showing very significant improvement in convergence rates at little cost.

On Multigrid Solution of High-Reynolds Incompressible Entering Flows*
An approach is presented for effectively separating the solution process of the elliptic component of high-Reynolds incompressible steady entering flow, for which classical multigrid techniques are well-suited, from that of the non-elliptic part, for which other methods are more effective. It is shown by analysis and numerical calculations that such an approach is very effective in terms of asy...
متن کاملA Multigrid Smoother for High Reynolds Number Flows∗
Abstract. The linearized Navier–Stokes equations are solved in two space dimensions using a multigrid method where a semiimplicit Runge–Kutta scheme is the smoother. Explicit time-integration in the streamwise direction is combined with implicit integration in the body-normal direction. Thereby the stiffness of the equations due to the disparate scales in the boundary layer is removed. Reynolds...
متن کاملDirectional Agglomeration Multigrid Techniques for High-Reynolds Number Viscous Flows
A preconditioned directional-implicit agglomeration algorithm is developed for solving twoand three-dimensional viscous flows on highly anisotropic unstructured meshes of mixed-element types. The multigrid smoother consists of a pre-conditioned pointor line-implicit solver which operates on lines constructed in the unstructured mesh using a weighted graph algorithm. Directional coarsening or ag...
متن کاملDirectional Coarsening and Smoothing for Anisotropic Navier-Stokes Problems
Unstructured multigrid techniques for relieving the stiffness associated with high-Reynolds number viscous flow simulations on extremely stretched grids are investigated. One approach consists of employing a semi-coarsening or directional-coarsening technique, based on the directions of strong coupling within the mesh, in order to construct more optimal coarse grid levels. An alternate approach...
متن کاملConvergence acceleration of Runge-Kutta schemes for solving the Navier-Stokes equations
The convergence of a Runge-Kutta (RK) scheme with multigrid is accelerated by preconditioning with a fully implicit operator. With the extended stability of the Runge-Kutta scheme, CFL numbers as high as 1000 can be used. The implicit preconditioner addresses the stiffness in the discrete equations associated with stretched meshes. This RK/implicit scheme is used as a smoother for multigrid. Fo...
