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


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

3D modeling

Item MECA_TETRA4.


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

Number of knots: 4

Number of meshes and types: 1 TETRA4


Tested features
-----------------------

The ENDO_ORTH_BETON law of behavior in simple compression (with load control).


Charging path
--------------------

The element is subjected to uniaxial traction in the :math:`X` direction. Move :math:`\mathrm{DX}` is imposed on node :math:`\mathrm{N1}`. The difference with B modeling is that we use the load control method PRED_ELAS (cf. doc. [:ref:`R5.03.80 <R5.03.80>`]).
