:class:`Air`
============


.. py:class:: ansys.dyna.core.pre.dynamaterial.Air(mass_density=0.00128, pressure_cutoff=-1e-09, initial_internal_energy=2.5331e-06, initial_relative_volume=1.0, equation_coefficient=[0, 0, 0, 0, 0.4, 0.4, 0])

   
   Defines an air material.


   :Parameters:

       **name** : :class:`python:str`
           Material name.

       **mass_density** : :class:`python:float`, :obj:`optional`
           Mass density. The default is ``0.00128``.

       **pressure_cutoff** : :class:`python:float`, :obj:`optional`
           pressure cutoff. The default is ``1e-09``.

       **initial_internal_energy** : :class:`python:float`, :obj:`optional`
           Initial internal energy per unit reference volume.
           The default is ``2.5331e-06``.

       **initial_relative_volume** : :class:`python:float`, :obj:`optional`
           Initial relative volume. The default is ``1.0``.

       **equation_coefficient** : :class:`python:list`, :obj:`optional`
           Six polynomial equation coefficient. The default is
           ``[0, 0, 0, 0, 0.4, 0.4, 0])``.



   :Returns:

       :ref:`bool <python:bltin-boolean-values>`
           ``True`` when successful, ``False`` when failed.
