ABSTRACT

In this paper, we propose and investigate a two-grid stabilized finite element method for the mixed dual-permeability-Stokes fluid flow model with Beavers-Joseph interface condition. First, a stabilized finite element scheme for the coupled dual-permeability-Stokes problem is addressed on a coarse grid. Subsequently, on a fine grid, we first solve the matrix and microfracture subproblems via approximating the interface terms by the coarse-grid approximation, and then the Stokes subproblem. The optimal error estimates are established, and a series of numerical experiments are presented to illustrate the effectiveness, efficiency, and robustness of the proposed algorithm.
