In addition to time-domain simulation methods, engineers from different application fields require further types of analysis to be performed on their systems. In particular results from frequency domain analysis play an important role - this includes the calculation of natural frequencies and vibration modes, but also the computation of transfer functions or the simulation of steady-state behaviour. If the system equations are formulated using the Modelica language, there is the potential to use one and the same model for time-domain as well as frequency-domain computations. In this paper it is shown how the different methods can be applied to a Modelica model, what kind of prerequisites and adjustments are required in order to perform the different types of analysis and how these methods can be seamlessly integrated into a Modelica simulation environment.
