2 The aim of the project ANSYS has been created as a problem oriented macro based tool which is integrated in ANSYS and makes it easier for the user to deal with rotor vibration problems. The main objective of creation of the tool was to use the maximum of ANSYS capabilities like creation of finite element model, elements library, computational procedures for solution of eigenvalues, mode shapes, harmonic vibration, transition vibration. A problem oriented user environment (UIDL) was created to make input parameters entry, specification of the analysis and results evaluation easy. The module is fully implemented into the environment of ANSYS.

4 The menu system
5 Setup of Units The user can define the units by selection from a couple of predefined groups that he would like to use in the analysis. Based on this selection a wizard (non-binding) for input parameters entry will appear, which will shows the units in which the system expects entered values.
