N modeling
==============


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

We use 3D modeling in non-linear mechanics with hyper-reduction of the model and
finite element correction (option CORR_COMPLET).


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

The mesh contains 216 elements of type HEXA8.


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

With CORR_COMPLET
~~~~~~~~~~~~~~~~~~

We test the value of the movements obtained with a hyper-reduced model (with correction) by
compared to those obtained in the complete model:

notes
---------

We can see that the calculation with CORR_COMPLET is a bit better on the evaluation of constraints,
but it's still not significant about travel.
