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

The modeling used is 3D.

Loading and boundary conditions are modelled by:


* DDL_IMPO: (NOEUD: N04, DX: 0., DY:0.)

DDL_IMPO: (NOEUD: N08, DX: 0., DY:0., DZ:0.)

DDL_IMPO: (NOEUD: N02, DX: 0.)

DDL_IMPO: (NOEUD: N06, DX: 0.)


* imposed surface forces (keyword FORCE_FACE) on the faces (skin elements) :math:`(\mathrm{1,}\mathrm{5,}6)`, :math:`(\mathrm{1,}\mathrm{2,}6)`, :math:`(\mathrm{1,}\mathrm{5,}7)`, :math:`(\mathrm{1,}\mathrm{3,}7)`, :math:`(\mathrm{3,}\mathrm{4,}7)`, :math:`(\mathrm{4,}\mathrm{7,}8)`, :math:`(\mathrm{2,}\mathrm{4,}6)` and :math:`(\mathrm{4,}\mathrm{6,}8)`.


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

Number of knots: 8

Number of meshes and types: 6 TETRA4 and 8 TRIA3 (faces)
