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


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

The **mesh method** of operator PROPA_FISS is used to propagate the crack.


Characteristics of the mesh
----------------------------

The mesh is the same as that of modeling A.


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

First of all, we test the number of pieces that make up the bottom of the crack at each propagation step:


.. csv-table::

    "**No propagation**", "**Reference type**", "**Reference value**"
    "1", "'ANALYTIQUE'", "4"
    "2", "'ANALYTIQUE'", "1"


The position of the bottom of the crack is also tested at each propagation step, which can be done by verifying the maximum value of the y coordinate of the bottom points:


.. csv-table::

    "**No propagation**", "**Reference type**", "**Reference value**"
    "1", "'ANALYTIQUE'", "16.0"
    "2", "'ANALYTIQUE'", "28.0"
