B modeling
==============

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

In modeling B, the same calculation is made as in modeling A, but by decomposing it into a first part where the fluid potential associated with the modes of structure of the reservoir is explicitly obtained.


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

The added mass of the first mode is calculated by projecting the fluid displacement potential onto itself. The result is compared with that given by the operator CALC_MATR_AJOU.


.. csv-table::

    "Identification", "Reference Type", "Reference Value", "Tolerance"
    "Mass added from the first mode on itself", "'AUTRE_ASTER'", "96633 kg", "0.1%"


The pressure and speed potentials are then deduced by a factor :math:`\omega` or :math:`{\omega }^{2}`, :math:`\omega` being the frequency of the mode in question.
