Blending Dual Time Stepping and Newton-Krylov Methods for Unsteady Flows
Blending Dual Time Stepping Newton-Krylov Methods Unsteady Flows
2015/7/3
We explore the idea of using nonlinear schemes as preconditioners in Newton-Krylov schemes for unsteady flow computations. Analysis shows that left preconditioning changes the Newton scheme in a...
