Energy stable and conservative dynamical low-rank approximation for the Su-Olson problem
Lena Baumann, Lukas Einkemmer, Christian Klingenberg +1
Computational methods for thermal radiative transfer problems exhibit high computational costs and a prohibitive memory footprint when the spatial and directional domains are finel…
A well-balanced semi-implicit IMEX finite volume scheme for ideal Magnetohydrodynamics at all Mach numbers
Claudius Birke, Walter Boscheri, Christian Klingenberg
We propose a second-order accurate semi-implicit and well-balanced finite volume scheme for the equations of ideal magnetohydrodynamics (MHD) including gravitational source terms.…
A finite-volume scheme for modeling compressible magnetohydrodynamic flows at low Mach numbers in stellar interiors
G. Leidi, C. Birke, R. Andrassy +5
Fully compressible magnetohydrodynamic (MHD) simulations are a fundamental tool for investigating the role of dynamo amplification in the generation of magnetic fields in deep conv…
Kinetic chemotaxis tumbling kernel determined from macroscopic quantities
Kathrin Hellmuth, Christian Klingenberg, Qin Li +1
Chemotaxis is the physical phenomenon that bacteria adjust their motions according to chemical stimulus. A classical model for this phenomenon is a kinetic equation that describes…
Well-balanced Central Scheme for the System of MHD Equations with Gravitational source term
Farah Kanbar, Rony Touma, Christian Klingenberg
A well-balanced second order finite volume central scheme for the magnetohydrodynamic (MHD) equations with gravitational source term is developed in this paper. The scheme is an un…
Computing Black Scholes with Uncertain Volatility-A Machine Learning Approach
Kathrin Hellmuth, Christian Klingenberg
In financial mathematics, it is a typical approach to approximate financial markets operating in discrete time by continuous-time models such as the Black Scholes model. Fitting th…
