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


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

The lyre is divided into 3 substructures, meshed in an identical manner and therefore conformal.

Moreover, the problem is solved on a global network. This makes it possible to compare the 2 approaches by calculating the MAC criterion (Modal Assurance Criterion).
