O modeling
==============


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

We use a 3D modeling in non-linear thermal 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
~~~~~~~~~~~~~~~~~~

The value of the temperatures obtained with a hyper-reduced model (with correction) is tested by
compared to those obtained in the complete model:

Without CORR_COMPLET
~~~~~~~~~~~~~~~~~~

The value of the temperatures obtained with a hyper-reduced model (without correction) is tested by
compared to those obtained in the complete model:


.. csv-table::

    "**Location**", "**Instant**", "**Component**", "Temperature", "**Precision**"
    "Knot in :math:`({1.5,1.5,3})` "," :math:`t=1s` "," TEMP "," ", "29.9070478306"," 0.007%"
    "Knot in :math:`({1.5,1.5,3})` "," :math:`t=4s` "," TEMP "," ", "139.467784038"," 0.0025%"
    "Knot in :math:`({1.5,1.5,3})` "," :math:`t=7s` "," TEMP "," ", "567.145887211"," 0.0009%"
    "Knot in :math:`({1.5,1.5,3})` "," :math:`t=10s` "," "," TEMP ", "999.500384048"," 0.00075%"



notes
---------

We can see that the calculation with CORR_COMPLET is a bit better on the evaluation of temperatures.
