B modeling
==============


Geometry and meshing
---------------------

The geometry and the mesh are the same as in modeling A.


Material properties
------------------------

For modeling B, damping is introduced using the Rayleigh coefficients defined in section 1.2.


Tested sizes and results
------------------------------

In this test, for the natural modes 2 and 3 of the assembly, we compare the phase difference between the real and imaginary parts of the movements of the three nodes represented by green dots in FIG. 1.1-1. We test the value of the ratio of the imaginary and real parts of the displacement. The results are summarised in table 3.3-1
