:class:`MatNull`
================


.. py:class:: ansys.dyna.core.pre.dynamaterial.MatNull(mass_density=0, pressure_cutoff=0)

   
   Defines a null material.

   Young's modulus and Poisson's ratio are used to set the contact stiffness.

   :Parameters:

       **mass_density** : :class:`python:float`, :obj:`optional`
           Mass density. The default is ``0``.

       **pressure_cutoff**
