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

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

The modeling is of the 3D type.

Loading and boundary conditions are modelled by:

.. code-block:: text

    FACE_IMPO =( _F (GROUP_MA = 'facexy', DZ= 0. ),
_F (GROUP_MA = 'facez', DY= 0. ),
_F (GROUP_MA = 'faceyz', DX= 0.))

The temperature TEMP1, drying SECH1, and hydration fields HYDR1 are applied to the entire model.

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

For the calculation with STAT_NON_LINE (with COMPORTEMENT), the components of the strain tensor EPSI_NOEU are tested after 3600 days. We also check that the stresses SIEF_NOEU are zero as well as the plastic deformation (EPSP_NOEU).

For the calculation with MECA_STATIQUE, the components of the EPSI_NOEU deformation tensor are tested after 3600 days. We also check that constraints SIGM_NOEU are zero.
