Reference solution
=====================

Calculation method used for the reference solution
--------------------------------------------------------

The reference is obtained for 6 modes with Castem 2000, for the modal recombination method CQC.


Benchmark results
----------------------

**Modal calculation**

Frequencies, effective masses next :math:`x,y,z`

**Static Mode**

Displacements at characteristic nodes

**Spectral response**

Generalized movements and efforts at characteristic nodes

Reaction to embedding

The results are obtained with 6 modes for modal recombination CQC.
