A robust matrix-free approach for large-scale non-isothermal high-contrast viscosity Stokes flow on blended domains with applications to geophysics
Andreas Burkhart, Nils Kohl, Barbara Wohlmuth +1
We consider a compressible Stokes problem in the quasi-stationary case coupled with a time dependent advection-diffusion equation with special emphasis on high viscosity contrast g…

The generalized scalar auxiliary variable applied to the incompressible Boussinesq Equation
Andreas Wagner, Barbara Wohlmuth, Jan Zawallich
This paper introduces a second-order time discretization for solving the incompressible Boussinesq equation. It uses the generalized scalar auxiliary variable (GSAV) and a backward…

A 3D-1D-0D Multiscale Model of the Neuro-Glial-Vascular Unit for Synaptic and Vascular Dynamics in the Dorsal Vagal Complex
Alexander Hermann, Tobias Köppl, Andreas Wagner +5
Cerebral blood flow regulation is critical for brain function, and its disruption is implicated in various neurological disorders. Many existing models do not fully capture the com…
