D modeling
==============


Characteristics of modeling
-----------------------------------

Modeling :math:`D` is almost the same as modeling :math:`A`. Only the D_ PLAN elements in the massif are modified. They are replaced by D_ PLAN_HMS elements. Thus, rather than a completely impermeable medium, we consider a medium with low permeability:


.. math::
: label: EQ-None

    \ textrm {Intrinsic permeability}
    {K} ^ {\ text {int}}

Exchanges between crack and massif are authorized for this modeling.

Discretization in time: 10 time steps of :math:`20s`.


Tested sizes and results
------------------------------

The following non-regression tests are simply performed:


.. csv-table::

    "**Point**", "**Time (** :math:`s` **)**", ":math:`\mathrm{Fy}` **(** :math:`\mathrm{kN}/{\mathrm{mm}}^{\mathrm{²}}` **)**
    **Aster**"
    ":math:`B` ", "100", "-11,87"
    ":math:`B` ", "200", "-2,10"



.. csv-table::

    ":math:`X` **(** :math:`\mathrm{mm}` **)**", ":math:`Y` **(** :math:`\mathrm{mm}` **)**", "**Time (** :math:`s` **)**", ":math:`\mathrm{PRE1}` **(** :math:`\mathrm{MPa}` **)**", "**(** **)**
    **Aster**"
    "0", "-41", "140", "0.0737"
    "0", "-41", "200", "0.1679"
