A Comparison of Multirate Co-Simulation Techniques for Field-Circuit Coupled Problems
Michael Wiesheu, Sebastian Schöps, Idoia Cortes Garcia
This paper compares three different multirate splitting approaches for the application on field-circuit coupled magnetoquasistatic simulations. For these methods, again three diffe…
Data-driven moving-window Bayesian inference for transient CO2-temperature network models of buildings
Zhijian Wang, Stein K. F. Stoter, Clemens V. Verhoosel +1
In this work, we proposes a CO2-temperature network model that links multi-zone mass transport and thermal dynamics through shared latent drivers, airflow and occupancy. The therma…
Waveform Relaxation for Field/Circuit Coupled DAEs with Generalized Capacitances
Idoia Cortes Garcia, Jonas Pade
Field/circuit coupling is a common approach when a lumped representation of a certain electrotechnical device is not accurate enough. To exploit existing code and underlying proper…
A topological decoupling of modified nodal analysis including controlled sources
Idoia Cortes Garcia, Peter F. Förster, Lennart Jansen +2
We derive a topological decoupling of the equations of modified nodal analysis (MNA) to a semi-explicit index one differential-algebraic equation. The decoupling explicitly allows…
Learning solutions of parameterized stiff ODEs using Gaussian processes
Idoia Cortes Garcia, P. Förster, W. Schilders +1
Stiff ordinary differential equations (ODEs) play an important role in many scientific and engineering applications. Often, the dependence of the solution of the ODE on additional…
