G modeling
==============


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

It is the same modeling as the E model, but in :math:`\mathrm{3D}`. The intersection is constructed in the same way.


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

The mesh, identical to that of modeling C, is represented in FIG. 5.2-a.


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

The movements at the level of the crack lips are tested after having carried out the post-treatment operations relating to :math:`\text{X-FEM}` (POST_MAIL_XFEM and POST_CHAM_XFEM). The DX displacement should follow function :math:`{u}_{x}` in equation 2.2-7. The displacement DY should follow function :math:`{u}_{y}` in equation 2.2-8. The DZ displacement should follow function :math:`{u}_{z}` in equation 2.2-9. The deformation shown in FIG. 7.4-a is obtained.
