Lower-Upper Symmetric-Gauss-Seidel Method for the Euler and Navier-Stokes Equations
نویسنده
چکیده
A NEW multigrid relaxation scheme is developed for the steady-state solution of the Euler and Navier-Stokes equations. The lower-upper Symmetric-Gauss-Seidel method (LUSGS) does not require flux splitting for approximate Newton iteration. The present method, which is vectorizable and unconditionally stable, needs only scalar diagonal inversions. Application to transonic flow shows that the new method is efficient and robust.

Fast preconditioned multigrid solution of the Euler and Navier-Stokes equations for steady, compressible flows
New versions of implicit algorithms are developed for the e cient solution of the Euler and Navier– Stokes equations of compressible ow. The methods are based on a preconditioned, lower-upper (LU) implementation of a non-linear, symmetric Gauss-Seidel (SGS) algorithm for use as a smoothing algorithm in a multigrid method. Previously, this method had been implemented for ows in quasi-onedimensio...

An implicit non-linear lower-upper symmetric Gauss-Seidel (LU-SGS) solution algorithm has been developed for a high-order spectral difference Navier-Stokes solver on unstructured hexahedral grids. The non-linear LU-SGS solver is preconditioned by a block element matrix, and the system of equations is then solved with the LU decomposition approach.
