Robust preconditioners for perturbed saddle-point problems and conservative discretizations of Biot's equations utilizing total pressure
Wietse M. Boon, Miroslav Kuchta, Kent-Andre Mardal +1
We develop robust solvers for a class of perturbed saddle-point problems arising in the study of a second-order elliptic equation in mixed form (in terms of flux and potential), an…
Analysis and approximation of mixed-dimensional PDEs on 3D-1D domains coupled with Lagrange multipliers
Miroslav Kuchta, Federica Laurino, Kent-Andre Mardal +1
Coupled partial differential equations defined on domains with different dimensionality are usually called mixed dimensional PDEs. We address mixed dimensional PDEs on three-dimens…
Robust preconditioning for coupled Stokes-Darcy problems with the Darcy problem in primal form
Karl Erik Holter, Miroslav Kuchta, Kent-Andre Mardal
The coupled Darcy-Stokes problem is widely used for modeling fluid transport in physical systems consisting of a porous part and a free part. In this work we consider preconditione…
Robust preconditioning of monolithically coupled multiphysics problems
Karl Erik Holter, Miroslav Kuchta, Kent-Andre Mardal
In many applications, one wants to model physical systems consisting of two different physical processes in two different domains that are coupled across a common interface. A cruc…
