We deal with the numerical solution of problems of incompressible flows and investigate the applicability of the Balancing Domain Decomposition by Constraints (BDDC) by [2] for solving the arising linear systems. In [5], we extended the multilevel version of BDDC ([7, 12]) to nonsymmetric problems arising from steady problems described by the Navier-Stokes equations.
