Algebraic multilevel preconditioners for non-symmetric PDEs on stretched grids.

Conference ·
OSTI ID:969878
We report on algebraic multilevel preconditioners for the parallel solution of linear systems arising from a Newton procedure applied to the finite-element (FE) discretization of the incompressible Navier-Stokes equations. We focus on the issue of how to coarsen FE operators produced from high aspect ratio elements.
