F modeling
==============


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

3D Modeling_ HH2S. This modeling corresponds to the Elements Finis modeling. The hydraulic coupling law is LIQU_AD_GAZ_VAPE. The mesh consists of 100 HEXA20 elements.


Results
---------

The results are very similar to those obtained with modeling finite volumes decentralized on the edge (modeling A).


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

Tests are carried out on 3 nodes at 1 moment by comparing the results with the analytical solution. We also test the first node in non-regression with an authorized relative error of :math:`\mathrm{0,01}\text{\%}`.
