6. D modeling#

6.1. Characteristics of modeling#

D modeling is*bidimensional* and*quasistatic*. It is identical to C modeling, except for three differences:

we use*sub-integrated modeling (MODELISATION = “D_ PLAN_HM_SI “) instead of classical modeling (MODELISATION = “D_ PLAN_HM”);

  • the saturated hydro-mechanical problem is resized by applying the resizing factors \({P}_{0}={10}^{+6}\) and \({K}_{0}={10}^{-5}\);

  • The convergence criterion used is RESI_REFE_RELA = 10-4, with SIGM_REFE = 1 and FLUX_HYD1_REFE = 1;

6.2. Characteristics of the mesh#

Unchanged compared to C modeling.

6.3. Tested sizes and results#

Unchanged compared to C modeling. Post-treatment should take into account the reverse transformation to the original units.

6.4. Comments#

These results validate the sub-integrated modeling and the resizing method.
