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


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

Same as modeling A, but using operators CREA_ELEM_SSD and ASSE_ELEM_SSD. The modal calculation of the direct model (not substructured) has not been repeated.


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

The values of the first 7 frequencies when stopped are shown in the table below.
