                         Abstract
A domain decomposition method for solving the Navier-Stokes
equations for almost incompressible flow is examined. Due to a
non-uniform decomposition of the domain, we have fast solvers in all
subdomains. Hence each iteration on the Schur-complement system can be
performed very efficiently. We have shown theoretically that the
method requires much less memory positions and arithmetic
operations than a direct method. Numerical experiments show that the
iteration on the Schur-complement system converges very fast. We also show
that the grid-quotient in the space-grid might be crucial for the
performance of the method. Moreover, we show that for a given
discretization of the problem, the rate of efficiency is larger than
100$\%$ for the problem studied here, due to the very nice
parallelization properties of the algorithm.
