C modeling
==============


Characteristics of modeling
-----------------------------------

The C modeling repeats the A modeling. The difference is the imposition of a speed transient on the rotating cracked rotor through a linear law of rotation speed.


Characteristics of the mesh

Results: comparison between 3D and 1D calculations
----------------------------------------------------

The same results as those of modeling A are found, summarized in the table.
