Co-simulation errors due to step size changes
Lars T. Kyllingstad
When two simulation units in a continuous-time co-simulation are connected via some variable , and both simulation units have an internal state which represents the time integra…
Error estimation and step size control with minimal subsystem interfaces
Lars T. Kyllingstad, Severin Sadjina, Stian Skjong
We review error estimation methods for co-simulation, in particular methods that are applicable when the subsystems provide minimal interfaces. By this, we mean that subsystems do…
Distributed Co-Simulation of Maritime Systems and Operations
Severin Sadjina, Lars T. Kyllingstad, Martin Rindarøy +7
Here, we present the concept of an open virtual prototyping framework for maritime systems and operations that enables its users to develop re-usable component or subsystem models,…
Energy Conservation and Power Bonds in Co-Simulations: Non-Iterative Adaptive Step Size Control and Error Estimation
Severin Sadjina, Lars T. Kyllingstad, Eilif Pedersen +1
Here, we study the flow of energy between coupled simulators in a co-simulation environment using the concept of power bonds. We introduce energy residuals which are a direct expre…
The chiral phase transition and the role of vacuum fluctuations
Jens O. Andersen, Rashid Khan, Lars T. Kyllingstad
We apply optimized perturbation theory to the quark-meson model at finite temperature T and quark chemical potential mu. The effective potential is calculated to one loop both in t…
The chiral phase transition and the role of vacuum fluctuations
Rashid Khan, Lars T. Kyllingstad
We investigate the chiral phase transition in the quark-meson effective model using optimised perturbation theory to one loop. Certain terms in the free energy are frequently omitt…
