A coupling concept for Stokes-Darcy systems: the ICDD method
Marco Discacciati, Paola Gervasio
We present a coupling framework for Stokes-Darcy systems valid for arbitrary flow direction at low Reynolds numbers and for isotropic porous media. The proposed method is based on…
Optimized Schwarz methods for the time-dependent Stokes-Darcy coupling
Marco Discacciati, Tommaso Vanzan
This paper derives optimal coefficients for optimized Schwarz iterations for the time-dependent Stokes-Darcy problem using an innovative strategy to solve a nonstandard min-max pro…
Optimized Neumann-Neumann method for the Stokes-Darcy problem
Marco Discacciati, Jake Robinson
A novel preconditioner of Neumann-Neumann type for the Stokes-Darcy problem is studied, where optimal weights of the local subproblems that define the preconditioner are obtained b…
A mixed FEM for the coupled Brinkman-Forchheimer/Darcy problem
Sergio Caucao, Marco Discacciati
This paper develops the a priori analysis of a mixed finite element method for the filtration of an incompressible fluid through a non-deformable saturated porous medium with heter…
