Modeling A
==============


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

We use a:


* 3D modeling and POU_D_E for the beam,


* A DIS_TRde element type POIau point C,


* 3D connection_ POUau point ATo connect the beam and the volume face,


* 3D connection_ POUau point C to connect the DIS_TRet element to the volume face.

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

The mesh contains 212 knots and 107 meshes including:


* 2 SEG2


* 24 SEG3


* 54 QUAD8,


* 27 HEXA20.
