What is a decompression model?
==============================

Nothing more than a bunch of volumes connected through vents! You can figure your A/C Layout:

.. _aicraft_layout:
.. figure:: fig/A330_layout.png
    :width: 400pt
    :align: center
    :alt: Aircraft layout
    :figclass: align-center
    :class: screenshot

    Aircraft Layout


As being a network of volumes:

.. _aicraft_model:
.. figure:: fig/A330_model.png
    :width: 400pt
    :align: center
    :alt: Aircraft model
    :figclass: align-center
    :class: screenshot

    Aircraft Model

Creating a model is just matter of describing this network, in terms of *volumes* and *vents*.

Additionally, some data about *load cases* need to be provided. By *load case*, we mean opening to ambient. 

How to fill the model template
------------------------------

This document describes how to build a reliable model. As of now, model are described *via* an excel spreadsheet embedding at
least three tabs:

*   Load_Cases (mandatory)
*   Volumes (mandatory)
*   Connections (mandatory)

Additionally, the following tabs may be included:

*   Dyn_Attributes (optional)

.. warning:: tabs name and columns headers are case-sensitive.

.. note:: Additional tabs are allowed and will be ignored.

.. include:: load_cases.rst
.. include:: volumes.rst 
.. include:: connections.rst 
.. include:: dyn_attributes.rst 


.. rubric:: Footnotes
.. [#mand] The value is mandatory, and has therefore no default value.
.. [#excl] Values are excluding each other. Only one of them need to be filled.
.. [#approx] This value will not affect calculations, but is used to
    present results in a comprehensive way. An accurate value is therefore not
    useful.
.. [#sym] symmetrized from <var>_i_to_j.  
.. [#hinged_only] Only used for rotating (hinged) panels ( -1 <= ``axis`` <= 1)
