The component Model Options in the General tab sheet determine how the component model is used in relation to the whole engine system model. The options depend on model type but in many cases determine what component performance variables are used as component states and/or error variables in the differential equations.
Often, the setting of an option in one component requires the a specific specific setting in another.
The fuel flow in the Manual Fuel control component can be specified as a 'free state' (instead as a user specified input parameter) in order to calculate an off-design operating point with a user specified gas generator rotor speed. This requires A compressor component model option to be set as "externally controlled rotor speed' and the 'Power balance at rotor speed' option for the gas generator turbine component.
