MeshNode object

The MeshNode object refers to a node of a native mesh or an orphan mesh. A MeshNode object can be accessed via a part or part instance using an index that refers to the internal numbering of the node repository. The index does not refer to the node label.

The following topics are discussed:

Node(...)

This method creates a node on an orphan mesh part.

Path

mdb.models[name].parts[name].Node

Required arguments

coordinates: A sequence of three Floats specifying the coordinates of the new node.

Optional arguments

localCsys: A DatumCsys object specifying the local coordinate system. If unspecified, the global coordinate system will be used.
label: An Int specifying the node label.

Return value

A MeshNode object.

Exceptions

None.

getElemEdges()

This method returns a tuple of element edge objects that share the node.

Arguments

None.

Return value

A tuple of MeshEdge objects.

Exceptions

None.

getElemFaces()

This method returns a tuple of element face objects that share the node.

Arguments

None.

Return value

A tuple of MeshFace objects.

Exceptions

None.

getElements()

This method returns a tuple of element objects that share the node.

Arguments

None.

Return value

A tuple of MeshElement objects.

Exceptions

None.

getNodesByFeatureEdge(...)

This method returns an array of mesh node objects that are obtained by recursively finding adjacent nodes along a feature edge that are at an angle of less than or equal to the specified face angle.

Required arguments

angle: A float specifying the value of the face angle in degrees.

Optional arguments

None.

Return value

A MeshNodeArray object, which is a sequence of MeshNode objects.

Exceptions

None.

setValues(...)

This method modifies the MeshNode object.

Required arguments

None.

Optional arguments

label: An Int specifying the node label. This member may only be edited if the node belongs to an orphan mesh part. The specified label must be non-negative and must not be in use by any other node of the same part.

Return value

None.

Exceptions

None.

Members

The MeshNode object has the following members:

label: An Int specifying the node label.
instanceName: A String specifying the name of the part instance that owns this node.
coordinates: A tuple of three Floats specifying the coordinates of the new node.
