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


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

It is the same modeling and the same mesh as the E modeling but in AXI. The models AXI_THH2MS, AXI_HH2MS,, AXI_THH2S and AXI_HH2S are tested successively.


Tested values and results
----------------------------

As before, it is verified that the water flow ('FH11X' + 'FH12X' recovered by SIEF_NOEU) obtained on the taxation edge corresponds to its analytical expression, namely :math:`q_{w}^{ext}{.}n= \alpha.\rho_{vp}.\left( exp\left[ \frac{Pc.M_{H2O}}{\rho_{l}.R.T}\right] -{HR}^{ext} \right)`. A tolerance of 10% is allowed due to the size of the mesh and the error generated by the interpolation at the node.

For reasons of saving time, models other than AXI_THH2MS will only be tested for 60 s. We check that the pressures at 60 s are all the same regardless of the models.
