Abstract:  We consider the stationary Stokes equations on a polygonal 
           domain whose boundary has more than one component, i.e., 
           flow with obstacles.  A two-level additive Schwarz 
           preconditioner is developed for the divergence-free nonconforming 
           P1 finite element.  The condition number of the preconditioned 
           system is shown to be bounded independent of mesh sizes and the 
           number of subdomains in the case of generous overlap.
