NUMERICAL SOLUTION OF 2-D EULER EQUATIONS WITH MULTIGRID

Havacılık ve Uzay Teknolojileri Dergisi, 2007
A multigrid scheme is applied to accelerate the convergence of numerical solution of two dimensional Euler equations to steady state. Cell-centered finite volume method with central differencing scheme is used for discretization. Explicit multistage time-

Time-Accurate Navier-Stokes Calculations with Approximately Factored Implicit Schemes

, 2004
The performance of the dual time method is improved by means of an inner iteration based on an LU-SGS driven FAS multigrid method, and by using the same LU-SGS method in a time-accurate mode to provide a starting solution for each dual time step. This
