D modeling
==============

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

We use 3D_SI and COQUE_SOLIDE models, linked by a LIAISON_MAILLE. We are in flexibility, linear isotropic elasticity, small deformations (ELAS/PETIT).


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

The part in 3D_SI modeling represents a quarter of the length of the beam, near the embedment. The rest of the beam is done in modeling COQUE_SOLIDE. The mesh is not coincident at the junction and this is done by a LIAISON_MAILLE.

The mesh is as follows:


* Number of knots: 3816


* Number of meshes and types: 720 HEXA9et 420 HEXA20
