This paper communicates on the implementation of Physics-based Solving in the Modelon Jet Propulsion library, driven by requirements from industrial jet engine design workflows. On- and off-design simulation modes are typically sequential and iterative steps in a model-based design process of jet engines. The solution Modelon provides – based on the Jet Propulsion Library, Optimica Compiler Toolkit, FMI Toolbox and pyFMI – enables performing a robust design of a gas turbine for a design point satisfying relevant constraints of typical off-design scenarios. This paper illustrates this workflow with component and system level examples.
