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


.. csv-table::

    "Number of knots:", "8"
    "Number of meshes:", "1 of type HEXA 8"
    "", "6 of type QUAD 4"


The following meshes are defined:


.. csv-table::

    ":math:`\text{S\_ARR}` "," :math:`\mathrm{NO3}\mathrm{NO7}\mathrm{NO8}\mathrm{NO4}`"
    ":math:`\text{S\_AVT}` "," :math:`\mathrm{NO1}\mathrm{NO2}\mathrm{NO6}\mathrm{NO5}`"
    ":math:`\text{S\_DRT}` "," :math:`\mathrm{NO1}\mathrm{NO5}\mathrm{NO8}\mathrm{NO4}`"
    ":math:`\text{S\_GCH}` "," :math:`\mathrm{NO3}\mathrm{NO2}\mathrm{NO6}\mathrm{NO7}`"
    ":math:`\text{S\_INF}` "," :math:`\mathrm{NO1}\mathrm{NO2}\mathrm{NO3}\mathrm{NO4}`"
    ":math:`\text{S\_SUP}` "," :math:`\mathrm{NO5}\mathrm{NO6}\mathrm{NO7}\mathrm{NO8}`"


The travel limit conditions imposed are:

On nodes :math:`\mathrm{NO1}`, :math:`\mathrm{NO2}`, :math:`\mathrm{NO3}`, and :math:`\mathrm{NO4}`: :math:`\mathrm{DZ}=0`

On nodes :math:`\mathrm{NO3}`, :math:`\mathrm{NO7}`, :math:`\mathrm{NO8}`, and :math:`\mathrm{NO4}`: :math:`\mathrm{DY}=0`

On nodes :math:`\mathrm{NO2}`, :math:`\mathrm{NO6}`, :math:`\mathrm{NO7}`, and :math:`\mathrm{NO8}`: :math:`\mathrm{DX}=0`

The load consists of the same drying field and the same nodal force, :math:`1/4` applied to the four nodes of :math:`\text{S\_SUP}`.

We test the deformations due to desiccation creep as well as the deformations related to the control variables at the first Gauss point of the cell :math:`{M}_{1}` for the order number 49 of the result concept:
