C modeling
==============


Purpose of modeling
-----------------------

The purpose of this modeling is to validate the use of the formula from DEFI_PRES_EC8 with FORCE_COQUE_FO from AFFE_CHAR_MECA.


Parameters
-----------

The parameters of modeling A. are retained.

Details
---------

The mesh is a cylinder with a bottom (and ceiling) modelled in DKT elements.
The bottom of the tank is recessed.
We apply the pressure from DEFI_FONC_EC8. The calculation is elastic.


Tested sizes and results
------------------------------

After ensuring that the deformation generally had the expected shape, non-regression tests were added at two points in the middle of the water level, the first with azimuth 0 and the second with azimuth 180°. 
The values don't matter here because they're non-regression tests.

The image below shows the deformation of the tank.
