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 Coupling Error Reduction in Non-Iterative Co-Simulations
Severin Sadjina, Eilif Pedersen
When simulators are energetically coupled in a co-simulation, residual energies alter the total energy of the full coupled system. This distorts the system dynamics, lowers the qua…
Spin-Orbit-Induced Spin, Charge, and Energy Transport in Diffusive Superconductors
Camilla Espedal, Peter Lange, Severin Sadjina +2
We consider the spin-orbit-induced spin Hall effect and spin swapping in diffusive superconductors. By employing the non-equilibrium Keldysh Green's function technique in the quasi…
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…
Intrinsic Spin Swapping
Severin Sadjina, Arne Brataas, A. G. Mal'shukov
Here, we study diffusive spin transport in two dimensions and demonstrate that an intrinsic analog to a previously predicted extrinsic spin swapping effect, where the spin polariza…
Inverse Spin Hall Effect in SNS Josephson Junctions
A. G. Mal'shukov, Severin Sadjina, Arne Brataas
We consider DC supercurrents in SNS junctions. Spin-orbit coupling in combination with Zeeman fields can induce an effective vector potential in the normal conductor. As a conseque…
