Abstract

For integration of subsystems co-simulation tools and master algorithms have to cope with the problem of restricted access to subsystem information. Especially for efficient handling of inherent properties like stiffness and direct feedthrough of industrial co-simulations additional subsystem information is mandatory. As provision of dedicated partial derivatives, especially regarding subsystem states, is complex and computationally expensive, recently a novel pre-step co-simulation approach for handling stiff system simulations based on formal subsystem transformations was proposed. The approach follows the idea of the Nearly Energy Preserving Coupling Element (NEPCE) scheme where exclusively subsystem inputs are modified for compensation of the co-simulation discretization error. This paper outlines a generalization of the presented pre-step co-simulation method for handling stiffness and direct feedthrough of subsystems. The generalized pre-step co-simulation algorithm is examined along a theoretical 2 DoF benchmark co-simulation example indicating outstanding co-simulation performance.
