The standard provides examples for possible procedures in the formation of the corresponding calculation model for planned or already existing objects. After creating the calculation model, mathematical equations describing the model with an appropriate number of degrees of freedom are derived and applied. Also described are the system definition by task description, definition of system boundaries, determination of the frequency range and the calculation method. During modelling, the selection of relevant degrees of freedom, the verification of the kinematic structure, the construction of the model structure, the modelling of the system boundaries as well as the determination of model parameters and characteristic functions are considered. At the stage of model control and adjustment, test run, plausibility test, checking the model refinement and model simplification are also described.
