:class:`Node`
=============

.. py:class:: ansys.dpf.core.nodes.Node(mesh, nodeid, index, coordinates)

   Encapsulates all properties of a node in the mesh.

   A node is created from the :class:`ansys.dpf.core.elements` or
   :class:`ansys.dpf.core.meshed_region` class.

   :param mesh: Mesh region that the node is contained in.
   :type mesh: :class:`ansys.dpf.core.meshed_region` class
   :param nodeid: ID of the node.
   :type nodeid: int
   :param index: Index of the node.
   :type index: int
   :param coordinates: List of ``[x, y, z]`` coordinates for the node.
   :type coordinates: list

   .. rubric:: Examples

   >>> import ansys.dpf.core as dpf
   >>> from ansys.dpf.core import examples
   >>> model = dpf.Model(examples.find_static_rst())
   >>> nodes = model.metadata.meshed_region.nodes

   >>> # Initialize a node from a nodes collection
   >>> node = nodes[0]

   Initialize a node from an element.

   >>> element = model.metadata.meshed_region.elements[0]
   >>> node = element.nodes[0]
