In this paper, we discuss the model order reduction problem for descriptor systems, that is,
systems with dynamics described by differential-algebraic equations. We focus on linear …

The application of high-temperature superconductors to accelerator magnets for future
particle colliders is under study. Numerical methods are crucial for an accurate evaluation of …

Purpose–The purpose of this paper is to review the mutual coupling of electromagnetic
fields in the magnetic vector potential formulation with electric circuits in terms of (modified) …

In this paper, we present an overview of existing and ongoing developments in multirate and
cosimulation. These are structured into thematical sections, providing general information on …

We present novel coupling schemes for partitioned multiphysics simulation that combine
four important aspects for strongly coupled problems: implicit coupling per time step, fast and …

In this paper, we propose an optimized field/circuit coupling approach for the simulation of
magnetothermal transients in superconducting magnets. The approach improves the …

The need for holistic simulation of complex systems becomes more and more apparent,
arising from different fields of application and approached by different scientific methods …

Starting from space-discretisation of Maxwell's equations, various classical formulations are
proposed for the simulation of electromagnetic fields. They differ in the phenomena …

In some applications, there arises the need of a spatially distributed description of a physical
quantity inside a device coupled to a circuit. Then, the in-space discretised system of partial …

While waveform relaxation (also known as dynamic iteration or co-simulation) methods are
known to converge for coupled systems of ordinary differential equations (ODEs), they may …
