L modeling
==============

The crack bottom is closed in X- FEM. Calculate :math:`G` with CALC_G_XFEM.


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

The advantage of this modeling is to start again from modeling A and to symmetrize the mesh.

Thus, we find the discretization of the corona of modeling A.

Only traction loading is taken into account.


Characteristics of the mesh

Number of knots: 18571

Number of meshes and type: 3136 HEXA20 and 1728 PENTA15
