Validation
==========


A to E models
-------------------

For each model, we test the value of TOUS the Gauss points of the integration diagrams.

The values of CH1 are tested in 'NON_REGRESSION'

The values of CH2 are tested in 'ANALYTIQUE'


F modeling
--------------

This modeling projects a field from a FEM tetrahedron cell to an X- FEM tetrahedron cell. Field CH1est is therefore stored on a single Gauss point, while field CH2est stored on a family of 90 Gauss points. In addition, the interface in question corresponds to the division of the tetrahedron element into 4 sub-tetrahedra, which implies that only 60 Gauss points out of the 90 available actually store a value.

Let :math:`C` be the value stored by the single Gauss point in field CH1. The first 60 Gauss points in field CH2stockent the value :math:`C`, while the last 30 Gauss points store the value 0, so the sum of the values of CH2est equal to :math:`60C` and the largest stored value is :math:`C`.

In order not to make the command file heavier by using 90 analytical value tests:


* The only value of CH1est tested in 'NON_REGRESSION',


* The sum of the values of CH2 and the largest value of CH2 are tested in 'ANALYTIQUE'.
