8. D modeling#
8.1. Characteristics of modeling#
The objective is to validate the compatibility of CALC_ESSAI_GEOMECA with Iwan’s law. The number of time increments is equal to 200. The initial containment pressure is :math:`{mathrm{sigma }}_{0}=50mathit{kPa}`. The convergence criterion is RESI_GLOB_RELA **** = 10-8.
8.2. Tested sizes and results#
The solutions are compared to the solution obtained directly by SIMU_POINT_MAT ** in the ssnv205b test case.
