This paper describes how to develop a mathematical model of a rotordynamical system for a reader either is a beginner or has a background in dynamical systems. The theory is described in order to conceive the main idea how to develop dynamical models of rotors. The problem is based on FEM and described in detail. The comparison of results is done with help of MATLAB code using the ROTORDYNAMIC TOOLBOX and Ansys modal analysis. The purpose of this paper, as mentioned above, is to identify why
