Node

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 ansys.dpf.core.elements or ansys.dpf.core.meshed_region class.

Parameters:

• mesh (ansys.dpf.core.meshed_region class) – Mesh region that the node is contained in.

• nodeid (int) – ID of the node.

• index (int) – Index of the node.

• coordinates (list) – List of [x, y, z] coordinates for the node.

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]

Overview

Properties

index	Index of the node. The index starts at 0.
id	ID of the node.
coordinates	Cartesian coordinates of the node.
nodal_connectivity	Elements indices connected to the node.

Special methods

__str__

Return string representation of the node.
