✦ Synopsis

This report considers the amount of parallelism attainable in certain robust domain decomposition methods for linearizations of the Navier-Stokes equations. The connection between parallelism and the finite element basis is shown in terms of the separation property of that basis, introduced in Section 2. Section 3 studies these questions in particular for the Navier-Stokes equations. Section 3 resolves the separation properties of common, low order spaces which satisfy the inf-sup condition, as well as introduces a new, low order space which has the (optimal) element separation property.

An algorithm based on the finite element modified method of characteristics (FEMMC) is presented to solve convection-diffusion, Burgers and unsteady incompressible Navier -Stokes equations for laminar flow. Solutions for these progressively more involved problems are presented so as to give numerica

## a b s t r a c t Based on the lowest equal-order conforming finite element subspace (X h , M h ) (i.e. P 1 -P 1 or Q 1 -Q 1 elements), a characteristic stabilized finite element method for transient Navier-Stokes problem is proposed. The proposed method has a number of attractive computational p
