Benchmark solution
=====================


Calculation method
------------------

Two types of calculations are carried out in order to test methods for manipulating generalized quantities.

The first modeling carries out a modal calculation and a harmonic response calculation on generalized quantities.

The second modeling carries out a modal calculation using the dynamic substructuring technique.


Reference quantities and results
------------------------

A cross-validation is carried out by comparing the results from the standard operators and the calculations carried out with the numpy library.

The natural frequencies obtained and the displacement field are checked for the harmonic response calculation.


Uncertainties about the solution
----------------------------

It is considered that there is a regression if the results obtained are not identical.
