3.2. Characteristics of the mesh

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

The following meshes are defined:

\(\text{S\_ARR}\)	\(\mathrm{NO3}\mathrm{NO7}\mathrm{NO8}\mathrm{NO4}\)
\(\text{S\_AVT}\)	\(\mathrm{NO1}\mathrm{NO2}\mathrm{NO6}\mathrm{NO5}\)
\(\text{S\_DRT}\)	\(\mathrm{NO1}\mathrm{NO5}\mathrm{NO8}\mathrm{NO4}\)
\(\text{S\_GCH}\)	\(\mathrm{NO3}\mathrm{NO2}\mathrm{NO6}\mathrm{NO7}\)
\(\text{S\_INF}\)	\(\mathrm{NO1}\mathrm{NO2}\mathrm{NO3}\mathrm{NO4}\)
\(\text{S\_SUP}\)	\(\mathrm{NO5}\mathrm{NO6}\mathrm{NO7}\mathrm{NO8}\)

The travel limit conditions imposed are:

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

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

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

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

We test the deformations due to desiccation creep as well as the deformations related to the control variables at the first Gauss point of cell \({M}_{1}\):
