In this article, a decoupling scheme based on two-grid finite element for the mixed Stokes-Darcy problem with the Beavers-Joseph interface condition is proposed and investigated. With a restriction of a physical parameter , we derive the numerical stability and error estimates for the scheme. Numerical experiments indicate that such two-grid based decoupling finite element schemes are feasible and efficient. (c) 2014 Wiley Periodicals, Inc.
