• Distributed Co-Simulation of Maritime Systems and Operations 

      Sadjina, Severin Simon; Kyllingstad, Lars Tandle; Rindarøy, Martin; Skjong, Stian; Æsøy, Vilmar; Pedersen, Eilif (ASME digital collection;OMAE-17-1037, Journal article; Peer reviewed, 2018-05)
      Here, we present the concept of an open virtual prototyping framework (VPF) for maritime systems and operations that enables its users to develop reusable component or subsystem models, and combine them in full-system ...
    • Energy conservation and coupling error reduction in non-iterative co-simulations 

      Sadjina, Severin Simon; Pedersen, Eilif (Journal article; Peer reviewed, 2019)
      When simulators are energetically coupled in a co-simulation, coupling errors alter the total energy of the full system. This distorts system dynamics, lowers the quality of the results, and can lead to instability. Using ...
    • Energy conservation and power bonds in co-simulations: non-iterative adaptive step size control and error estimation 

      Sadjina, Severin Simon; Kyllingstad, Lars Tandle; Skjong, Stian; Pedersen, Eilif (Journal article; Peer reviewed, 2017-07)
      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 expression of the coupling errors and, hence, ...
