A primal mixed domain decomposition procedure based on the nonconforming streamline diffusion method Original Research Article

A nonoverlapping iterative domain decomposition procedure by nonconforming primal mixed finite elements is proposed for convection–diffusion problems. We use the nonconforming streamline diffusion method to resolve convection dominated problems, and Robin-type boundary conditions to transmit information between subdomains. The convergence of the parallel iterative procedure is shown in detail and numerical examples are given.
