Preconditioning of a hybridizable discontinuous Galerkin method for the coupled Stokes--Darcy system

Esteban Henríquez, Miroslav Kuchta, Jeonghun J. Lee +1

We propose parameter-robust preconditioners for the statically condensed linear system arising from a hybridizable discontinuous Galerkin discretization of the coupled Stokes--Darc…

Parameter-robust preconditioners for a cell-by-cell poroelasticity model with interface coupling

Marius Causemann, Miroslav Kuchta

This paper presents a scalable and robust solver for a cell-by-cell poroelasticity model, describing the mechanical interactions between brain cells embedded in extracellular space…

Analysis of a Discontinuous Galerkin Method for Diffusion Problems on Intersecting Domains

Miroslav Kuchta, Rami Masri, Beatrice Riviere

The interior penalty discontinuous Galerkin method is applied to solve elliptic equations on either networks of segments or networks of planar surfaces, with arbitrary but fixed nu…

A Discontinuous Galerkin Method for the Extracellular Membrane Intracellular Model

Rami Masri, Keegan L. A. Kirk, Eirill Hauge +1

We formulate and analyze interior penalty discontinuous Galerkin methods for coupled elliptic PDEs modeling excitable tissue, represented by intracellular and extracellular domains…

A splitting, discontinuous Galerkin solver for the cell-by-cell electroneutral Nernst-Planck framework

Ada J. Ellingsrud, Pietro Benedusi, Miroslav Kuchta

Mathematical models for excitable tissue with explicit representation of individual cells are highly detailed and can, unlike classical homogenized models, represent complex cellul…
