On nonlinear preconditioners in Newton–Krylov methods for unsteady flows
The application of nonlinear schemes like dual time stepping as preconditioners in matrix-free Newton– Krylov-solvers is considered and analyzed, with a special emphasis on unsteady viscous flows. We provide a novel formulation of the left preconditioned operator that says it is in fact linear in the matrix-free sense, but changes the Newton scheme. This allows to get some insight in the conver...
متن کاملFully implicit Lagrange-Newton-Krylov-Schwarz algorithms for boundary control of unsteady incompressible flows
We develop a parallel fully implicit domain decomposition algorithm for solving optimization problems constrained by time dependent nonlinear partial differential equations. In particular, we study the boundary control of unsteady incompressible Navier-Stokes equations. After an implicit discretization in time, a fully coupled sparse nonlinear optimization problem needs to be solved at each tim...
متن کاملFractional Time-Stepping Methods for Unsteady Flow Problems
We study accuracy of fractional time-stepping (FTS) methods such as the alternating direction implicit method for the computation of heat ows and the velocity-pressure splitting methods for Navier-Stokes ows. The FTS techniques can be viewed as a perturbation of conventional temporal-spatial discretization schemes; they in theory invoke a perturbation error that is on the same order as the disc...
متن کاملKrylov Methods for Compressible Flows
In this paper we investigate the application of Krylov methods to compressible ows, and the e ect of implicit boundary conditions on the implicit solution of nonlinear problems. Two defect-correction procedures, namely, Approximate Factorization (AF) for structured grids, and ILU/GMRES for general grids are considered. Also, considered here, is Newton-Krylov matrix-free methods that we combine ...
متن کاملEfficient Implicit Time-Marching Methods Using a Newton-Krylov Algorithm
The numerical behavior of two implicit time-marching methods is investigated in solving two-dimensional unsteady compressible flows. The two methods are the second-order multistep backward differencing formula and the fourth-order multistage explicit first stage, single-diagonal coefficient, diagonally implicit Runge-Kutta scheme. A Newton-Krylov method is used to solve the nonlinear problem ar...
