E modeling: method SIMPLEXE
================================


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

An auxiliary grid is not used. We're going to test option ZONE_MAJ. The radius of the cylinder (:math:`4\mathrm{mm}`) coincides with that of the torus imposed by RAYON_TORE in PROPA_FISS.


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

The mesh is composed of 1000 elements of type HEXA8. The edge length of the mesh elements is :math:`1\mathrm{mm}`.

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

We test that the maximum and minimum values of the difference field are equal to zero.

So option ZONE_MAJ correctly calculates the group of nodes where the crack level-sets have been updated.
