Coupling deal.II and FROSch: A Sustainable and Accessible (O)RAS Preconditioner
Alexander Heinlein, Sebastian Kinnewig, Thomas Wick
In this work, restricted additive Schwarz (RAS) and optimized restricted additive Schwarz (ORAS) preconditioners from the Trilinos package FROSch (Fast and Robust Overlapping Schwa…
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…
Soliton compression and supercontinuum spectra in nonlinear diamond photonics
O. Melchert, S. Kinnewig, F. Dencker +9
We numerically explore synthetic crystal diamond for realizing novel light sources in ranges which are up to now difficult to achieve with other materials, such as sub-10-fs pulse…
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…
