v2.04.132 SDLV132 - Taking into account, by sub-structuring, of a generalized mass in a modal tree-line calculation

Summary:

This test makes it possible to validate the consideration, by substructuring, of a generalized mass for a tree line calculation.

In this test, we have a rotor model with a constant circular section resting on a mass by means of bearings considered to be infinitely rigid. This example is taken from the qualification manual for CADYRO, a finite element software program designed to model the dynamic behavior of rotors.
