Operator splitting for semi-explicit differential-algebraic equations and port-Hamiltonian DAEs
Andreas Bartel, Malak Diab, Andreas Frommer +1
Operator splitting methods allow to split the operator describing a complex dynamical system into a sequence of simpler subsystems and treat each part independently. In the modelin…
Characteristic Boundary Condition for Thermal Lattice Boltzmann Methods
Friedemann Klass, Alessandro Gabbana, Andreas Bartel
We introduce a non-reflecting boundary condition for the simulation of thermal flows with the lattice Boltzmann Method (LBM). We base the derivation on the locally one-dimensional…
Port-Hamiltonian Systems Modelling in Electrical Engineering
Andreas Bartel, Markus Clemens, Michael Günther +2
The port-Hamiltonian modelling framework allows for models that preserve essential physical properties such as energy conservation or dissipative inequalities. If all subsystems ar…
Operator Splitting Based Dynamic Iteration for Linear Port-Hamiltonian Systems
Andreas Bartel, Michael Günther, Birgit Jacob +1
A dynamic iteration scheme for linear differential-algebraic port-Hamil\-tonian systems based on Lions-Mercier-type operator splitting methods is developed. The dynamic iteration i…
Spline-oriented inter/extrapolation-based multirate schemes of higher order
Kevin Schäfers, Andreas Bartel, Michael Günther +1
Multirate integration uses different time step sizes for different components of the solution based on the respective transient behavior. For inter/extrapolation-based multirate sc…
Large-scale convective flow sustained by thermally active Lagrangian tracers
Lokahith Agasthya, Andreas Bartel, Luca Biferale +2
Non-isothermal particles suspended in a fluid lead to complex interactions -- the particles respond to changes in the fluid flow, which in turn is modified by their temperature ano…
