Preconditioning the Pseudo-Laplacian for finite element simulation of incompressible flow

Meyer, A. 30 October 1998 (has links) (PDF)
In this paper, we investigate the question of the spectrally equivalence of the so- called Pseudo-Laplacian to the usual discrete Laplacian in order to use hierarchical preconditioners for this more complicate matrix. The spectral equivalence is shown to be equivalent to a Brezzi-type inequality, which is fulfilled for the finite element spaces considered here.
