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…
Physics-Regularized Multi-Modal Image Assimilation for Brain Tumor Localization
Michal Balcerak, Tamaz Amiranashvili, Andreas Wagner +7
Physical models in the form of partial differential equations serve as important priors for many under-constrained problems. One such application is tumor treatment planning, which…
A phase-field model for non-small cell lung cancer under the effects of immunotherapy
Andreas Wagner, Pirmin Schlicke, Marvin Fritz +4
Formulating tumor models that predict growth under therapy is vital for improving patient-specific treatment plans. In this context, we present our recent work on simulating non-sm…
A matrix-free ILU realization based on surrogates
Daniel Drzisga, Andreas Wagner, Barbara Wohlmuth
Matrix-free techniques play an increasingly important role in large-scale simulations. Schur complement techniques and massively parallel multigrid solvers for second-order ellipti…
A 1D-0D-3D coupled model for simulating blood flow and transport processes in breast tissue
Marvin Fritz, Tobias Köppl, J. Tinsley Oden +3
In this work, we present mixed dimensional models for simulating blood flow and transport processes in breast tissue and the vascular tree supplying it. These processes are conside…
