Divergence-free decoupled finite element methods for incompressible flow problems
Volker John, Xu Li, Christian Merdon
Incompressible flows are modeled by a coupled system of partial differential equations for velocity and pressure, Starting from a divergence-free mixed method proposed in [John, Li…

Reduced Basis Approach for Convection-Diffusion Equations with Non-Linear Boundary Reaction Conditions
Sebastian Matera, Christian Merdon, Daniel Runge
This paper aims at an efficient strategy to solve drift-diffusion problems with non-linear boundary conditions as they appear, e.g., in heterogeneous catalysis. Since the non-linea…

Strain distribution in zincblende and wurtzite GaAs nanowires bent by a one-sided (In, Al)As stressor shell: consequences for torsion, chirality, and piezoelectricity
Yiannis Hadjimichael, Oliver Brandt, Christian Merdon +2
We present a finite-strain model that is capable of describing the large deformations in bent nanowire heterostructures. The model incorporates a nonlinear strain formulation deriv…
