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


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

The beam is divided into 2 substructures, meshed differently and not in accordance with the interface.

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).


Characteristics of the mesh
----------------------------

Beam 1

Number of knots: 756

Number of meshes and types: 50 QUAD4 and 500 HEXA8

Beam 2

Number of knots: 425

Number of meshes and types: 16 QUAD4 and 256 HEXA8

Global beam

Number of knots: 1476

Number of meshes and types: 25 QUAD4 and 1000 HEXA8


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

We test the values of the MAC matrix.
