C modeling
==============


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

Modeling: 3D.

The structure is a healthy rectangular parallelepipedic, in which an interface is introduced directly into the command file using the DEFI_FISS_XFEM [:ref:`U4.82.08 <U4.82.08>`] operator. The interface is present at a distance :math:`{L}_{Y}\mathrm{=}\mathrm{1,8}m` from the top edge of the plate.


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

Number of knots: 8644

Number of meshes and types: 6989

including TRIA6: 2600

including TETRA10 :4389


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

The movements resulting from the operator STAT_NON_LINE are post-processed in order to recover the values at the nodes of the crack from the new mesh.
