    "N2:

    N6:", ":math:`{U}_{x}={U}_{y}={U}_{z}=0`
    :math:`{U}_{x}={U}_{z}=0`
    :math:`{U}_{x}={U}_{y}=0` "," :math:`\mathit{N9},\mathit{N13},\mathit{N14},\mathit{N5},\mathit{N17}`: :math:`{U}_{x}=0`"


**Load:** Imposed displacement on face :math:`\mathrm{[}348711161915\mathrm{]}` + assignment of the same temperature on all nodes. The total number of increments is 21 (1 increment between :math:`t\mathrm{=}\mathrm{0s}` and :math:`1s`, 20 increments between :math:`t=1s` and :math:`2s`). The measurement of the deformations is of type SIMO_MIEHE

Convergence is achieved if the residue is less than or equal to RESI_GLOB_RELA = 10—6.
