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

A new multilevel smoothing method for wavelet-based algebraic multigrid poisson problem solver

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
In contrast to the standard algebraic multigrid, the Wavelet-based Algebraic Multigrid method relies more strongly on the smoothing method because the coarse spaces are chosen a priori. So, it is very important to develop new smoother methods, especially

Unstructured multigrid through agglomeration

, 1993
In this work the compressible Euler equations are solved using finite volume techniques on unstructured grids. The spatial discretization employs a central difference approximation augmented by dissipative terms.
