A Mixed Approach to the Poisson Problem with Line Sources
(Journal article; Peer reviewed, 2021)In this work we consider the dual-mixed variational formulation of the Poisson equation with a line source. The analysis and approximation of this problem is nonstandard, as the line source causes the solutions to be ... -
Robust Discretization of Flow in Fractured Porous Media
(Peer reviewed; Journal article, 2018)Flow in fractured porous media represents a challenge for discretization methods due to the disparate scales and complex geometry. Herein we propose a new discretization, based on the mixed finite element method and mortar ... -
Robust Linear Domain Decomposition Schemes for Reduced Nonlinear Fracture Flow Models
(Journal article; Peer reviewed, 2021)In this work, we consider compressible single-phase flow problems in a porous medium containing a fracture. In the fracture, a nonlinear pressure-velocity relation is prescribed. Using a non-overlapping domain decomposition ...
