E modeling
==============


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

3D Modeling_ HH2SUDA. This modeling corresponds to the Finite Volume modeling centered on the edges for mobilities (Fickian terms are centered). The hydraulic coupling law is LIQU_AD_GAZ_VAPE. The mesh consists of 100 HEXA27 elements.


Results
---------

The results are identical to those obtained with finite volume modeling off-centered on the edge (modeling A).


Tested values
---------------

Tests are carried out on 3 nodes at :math:`t\mathrm{=}100s` by comparing the results to the analytical solution. We also test the first node in non-regression with an authorized relative error of :math:`\mathrm{0,01}\text{\%}`.
