In this paper, we consider approximation of a second-order elliptic problem de ned on a domain in two-dimensional Euclidean space. Partitioning the domain into two subdomains, we consider a technique proposed by Wieners and Wohlmuth [9] for coupling mixed nite element approximation on one subdomain with a standard nite element approximation on the other.
