Summary: We consider an advection-diffusion problem. We write a Schur type formulation by using outflow boundary conditions on the interfaces. The condensed problem is solved by either a Jacobi algorithm (equivalent to an additive Schwarz method), GMRES, or BiCGstab. The use of outflow boundary conditions and of general iterative methods gives much better results than the original Schwarz method.
