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…
On the wave equation with space dependent coefficients: singularities and lower order terms
Marco Discacciati, Claudia Garetto, Costas Loizou
This paper complements the study of the wave equation with discontinuous coefficients initiated in \cite{DGL:22} in the case of time-dependent coefficients. Here we assume that the…
