Computational Multiscale Methods for Linear Poroelasticity with High Contrast
Shubin Fu, Robert Altmann, Eric T. Chung +3
In this work, we employ the Constraint Energy Minimizing Generalized Multiscale Finite Element Method (CEM-GMsFEM) to solve the problem of linear heterogeneous poroelasticity with…
A PDAE formulation of parabolic problems with dynamic boundary conditions
Robert Altmann
The weak formulation of parabolic problems with dynamic boundary conditions is rewritten in form of a partial differential-algebraic equation. More precisely, we consider two dynam…
Quantitative Anderson localization of Schrödinger eigenstates under disorder potentials
Robert Altmann, Patrick Henning, Daniel Peterseim
This paper concerns spectral properties of linear Schrödinger operators under oscillatory high-amplitude potentials on bounded domains. Depending on the degree of disorder, we prov…
Computational multiscale methods for linear heterogeneous poroelasticity
Robert Altmann, Eric Chung, Roland Maier +2
We consider a strongly heterogeneous medium saturated by an incompressible viscous fluid as it appears in geomechanical modeling. This poroelasticity problem suffers from rapidly o…
