NodeSet(...)

This method creates a node set from an array of OdbMeshNode objects (for part instance-level sets) or from a sequence of arrays of OdbMeshNode objects (for assembly-level sets).

Path

session.odbs[name].parts[name].NodeSet

session.odbs[name].rootAssembly.instances[name].NodeSet

session.odbs[name].rootAssembly.NodeSet

Required arguments

name

A String specifying the name of the set and the repository key.

nodes

A sequence of OdbMeshNode objects. For example, for a part:

nodes=part1.nodes[1:5]

For an assembly:

nodes=(instance1.nodes[6:7], instance2.nodes[1:5])

Optional arguments

None.

Return value

An OdbSet object.

Exceptions

InvalidNameError.

NodeSetFromNodeLabels(...)

This method creates a node set from a sequence of node labels.

Path

session.odbs[name].parts[name].NodeSetFromNodeLabels

session.odbs[name].rootAssembly.instances[name].NodeSetFromNodeLabels

session.odbs[name].rootAssembly.NodeSetFromNodeLabels

Required arguments

name

A String specifying the name of the set and the repository key.

nodeLabels

A sequence of node labels. A node label is a sequence of Int node identifiers. For example, for a part:

nodeLabels=(2,3,5,7)

For an assembly:

nodeLabels=(('Instance-1', (2,3,5,7)), ('Instance-2', (1,2,3)))

Optional arguments

None.

Return value

An OdbSet object.

Exceptions

InvalidNameError.

ElementSet(...)

This method creates an element set from an array of OdbMeshElement objects (for part instance-level sets) or from a sequence of arrays of OdbMeshElement objects (for assembly-level sets).

Path

session.odbs[name].parts[name].ElementSet

session.odbs[name].rootAssembly.instances[name].ElementSet

Required arguments

name

A String specifying the name of the set and the repository key.

elements

A sequence of OdbMeshElement objects. For example, for a part:

elements=instance1.elements[1:5]

For an assembly:

elements=(instance1.elements[1:5], instance2.elements[1:5])

Optional arguments

None.

Return value

An OdbSet object.

Exceptions

InvalidNameError.

ElementSetFromElementLabels(...)

This method creates an element set from a sequence of element labels.

Path

session.odbs[name].parts[name].ElementSetFromElementLabels

session.odbs[name].rootAssembly.instances[name].ElementSetFromElementLabels

session.odbs[name].rootAssembly.ElementSetFromElementLabels

Required arguments

name

A String specifying the name of the set and the repository key.

elementLabels

A sequence of element labels. An element label is a sequence of Int element identifiers. For example, for a part:

elementLabels=(2,3,5,7)

For an assembly:

elementLabels=(('Instance-1', (2,3,5,7)), ('Instance-2', (1,2,3)))

Optional arguments

None.

Return value

An OdbSet object.

Exceptions

InvalidNameError.

MeshSurface(...)

This method creates a surface from the element and side identifiers for the assembly.

Path

session.odbs[name].parts[name].MeshSurface

session.odbs[name].rootAssembly.instances[name].MeshSurface

session.odbs[name].rootAssembly.MeshSurface

Required arguments

name

A String specifying the name of the set and the repository key.

meshSurfaces

A sequence of sequences. Each sequence consists of an element sequence and a side identifier. The possible side identifiers depend on the type of element, as described in the following table:


Sequence of elements	Side identifiers
Solid elements	FACE1, FACE2, FACE3, FACE4, FACE5, FACE6
Three-dimensional shell elements	SIDE1, SIDE2
Two-dimensional elements	FACE1, FACE2, FACE3, FACE4
Wire elements	END, END2

For example:

side1Elements=instance1.elements[217:218]
side2Elements=instance2.elements[100:105]
assembly.MeshSurface(name='Surf-1',
meshSurfaces=((side1Elems,SIDE1),
(side2Elems,SIDE2)))

Optional arguments

None.

Return value

An OdbSet object.

Exceptions

InvalidNameError.

MeshSurfaceFromElsets(...)

This method creates a mesh surface from a sequence of element sets.

Path

session.odbs[name].parts[name].MeshSurfaceFromElsets

session.odbs[name].rootAssembly.instances[name].MeshSurfaceFromElsets

session.odbs[name].rootAssembly.MeshSurfaceFromElsets

Required arguments

name

A String specifying the name of the set and the repository key.

elementSetSeq

A sequence of element sets. For example,

elementSetSeq=((elset1,SIDE1),(elset2,SIDE2))

where elset1=session.odbs[name].rootAssembly.elementSets['Clutch'] and SIDE1 and SIDE2 indicate the side of the element set.

Optional arguments

None.

Return value

An OdbSet object.

Exceptions

InvalidNameError.

MeshSurfaceFromLabels(...)

This method creates a mesh surface from a sequence of surface labels.

Path

session.odbs[name].parts[name].MeshSurfaceFromLabels

session.odbs[name].rootAssembly.instances[name].MeshSurfaceFromLabels

session.odbs[name].rootAssembly.MeshSurfaceFromLabels

Required arguments

name

A String specifying the name of the set and the repository key.

surfaceLabels

A sequence of surface labels. For example,

surfaceLabels=(('Instance-1', ((10, FACE1), (11, FACE2))), 
('Instance-2', ((10, FACE3), (12, FACE4))))

where 10 is an element number and FACE1 indicates the side of the element.

Optional arguments

None.

Return value

An OdbSet object.

Exceptions

InvalidNameError.

Members

The OdbSet object can have the following members:

name: A String specifying the name of the set and the repository key.
instanceNames: A tuple of Strings specifying the namespaces for the nodes, elements, and faces; None if the set is on a Part or an OdbInstance object.
nodes: An OdbMeshNodeArray object specifying the nodes of an OdbSet. If a set spans more than one part instance, this member is a sequence of sequences for each part instance.
elements: An OdbMeshElementArray object specifying the elements of an OdbSet. If a set spans more than one part instance, this member is a sequence of sequences for each part instance.
faces: A tuple of SymbolicConstants specifying the element face. If a set spans more than one part instance, this member is a sequence of sequences for each part instance.
instances: A repository of an OdbInstance object.
isInternal: A Boolean specifying whether the set is internal.
