New substructuring domain decomposition methods for advection-diffusion equations
Two methods that generalise the well-known Neumann-Neumann and Dirichlet-Neumann iterative procedures and use symmetric and positive definite preconditioners, are proposed for the nonsymmetric elliptic problem. Optimal convergence properties are shown to exist.
