A two-level additive Schwarz preconditioner for the stationary Stokes equations
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. © 1995 J.C.
