Accelerated domain decomposition iterative procedures for mixed methods based on Robin transmission conditions
The article is concerned with mixed finite element approximations to elliptic boundary value problems, studied in detail for a model Neumann problem. The authors propose an iterative procedure based on non-overlapping or overlapping domain decompositions. As interfacial transmission condition, a Robin type boundary condition is used. The parameter in the condition and the overlap are systematically changed during the iteration to accelerate convergence.
