Mathematical modeling and numerical multigoal-oriented a posteriori error control and adaptivity for a stationary, nonlinear, coupled flow temperature model with temperature dependent density
Sven Beuchler, Ayhan Demircan, Bernhard Endtmayer +2
In this work, we develop adaptive schemes using goal-oriented error control for a highly nonlinear flow temperature model with temperature dependent density. The dual-weighted resi…
Algorithmic realization of the solution to the sign conflict problem for hanging nodes on hp-hexahedral Nédélec elements
Sebastian Kinnewig, Thomas Wick, Sven Beuchler
In this work, Nédélec elements on locally refined meshes with hanging nodes are considered. A crucial aspect is the orientation of the hanging edges and faces. For non-orientable m…
Hierarchical LU preconditioning for the time-harmonic Maxwell equations
Maryam Parvizi, Amirreza Khodadadian, Sven Beuchler +1
The time-harmonic Maxwell equations are used to study the effect of electric and magnetic fields on each other. Although the linear systems resulting from solving this system using…
Multigoal-oriented a posteriori error control for heated material processing using a generalized Boussinesq model
S. Beuchler, B. Endtmayer, J. Lankeit +1
In this work, we develop a posteriori error control for a generalized Boussinesq model in which thermal conductivity and viscosity are temperature-dependent. Therein, the stationar…
Parallel domain decomposition solvers for the time harmonic Maxwell equations
Sven Beuchler, Sebastian Kinnewig, Thomas Wick
The time harmonic Maxwell equations are of current interest in computational science and applied mathematics with many applications in modern physics. In this work, we present para…
