geometry.Geometry.add_set

Geometry.add_set(indices, type='node', name=None)

Add a Set of nodes or elements to the Geometry.

Sets are named groups of nodes or elements that can be used for selection, boundary conditions, or other topological operations.

Parameters

indicesarray_like

A list or array of node or element indices defining the set.

typestr, optional

The type of the set. Must be one of the types supported by the geometry (e.g. ‘node’, ‘elem’). Default is ‘node’.

namestr, optional

The name of the set. If not provided, an automatic name like ‘set-0’ will be assigned.

Returns

Set

The created and stored Set object.

Examples

>>> M = Mesh(eltype="quad4").subdivide(2)
>>> M.add_set([0, 1, 2], name="set_nodes")
Set(name='set_nodes', type='node', size=3)
>>> M.add_set([2, 3], type="elem")
Set(name='set-0', type='elem', size=2)

>>> print(M.set_report())
Set 'set_nodes', type 'node', size 3
Set 'set-0', type 'elem', size 2
>>> M.del_set('set-0')
>>> print(M.set_report())
Set 'set_nodes', type 'node', size 3
