3.1. Characteristics of modeling#
Boundary conditions:
N2: NO. 1: N6: |
\({U}_{x}={U}_{y}={U}_{z}=0\) \({U}_{x}={U}_{z}=0\) \({U}_{x}={U}_{y}=0\) |

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