`from_scoping`#

class ansys.dpf.core.operators.mesh.from_scoping.from_scoping(scoping=None, inclusive=None, nodes_only=None, mesh=None, config=None, server=None)#

Bases: ansys.dpf.core.dpf_operator.Operator

Extracts a meshed region from another meshed region based on a scoping. Regarding the property fields whose scoping location is ‘Elemental’, ‘Faces’, and ‘Nodal’, they are scoped to the elements, faces or nodes of the output mesh. The ones whose scoping location is ‘Global’ are transferred from the input mesh to the output mesh without changes, and the rest of the property fields are not present in the output mesh.

Inputs#

scoping: Scoping: if nodal/face scoping, then the scoping is transposed respecting the inclusive pin
inclusive: int, optional: if inclusive == 1 then all the elements/faces adjacent to the nodes/faces ids in input are added, if inclusive == 0, only the elements/faces which have all their nodes/faces in the scoping are included
nodes_only: bool, optional: returns mesh with nodes only (without any elements or property fields). Default is false.

mesh: MeshedRegion

Outputs#

mesh: MeshedRegion

Examples

>>> from ansys.dpf import core as dpf

>>> # Instantiate operator
>>> op = dpf.operators.mesh.from_scoping()

>>> op.inputs.nodes_only.connect(my_nodes_only)
>>> my_mesh = dpf.MeshedRegion()

...     scoping=my_scoping,
...     inclusive=my_inclusive,

You can modify the copy of the configuration and then use operator.config = new_config or instantiate an operator with the new configuration as a parameter.

For information on an operator’s options, see the documentation for that operator.

Returns:: Copy of the operator’s current configuration.
Return type:: ansys.dpf.core.config.Config

Modify the copy of an operator’s configuration and set it as current config of the operator.

>>> from ansys.dpf import core as dpf
>>> op = dpf.operators.math.add()
>>> config_add = op.config
>>> config_add.set_work_by_index_option(True)
>>> op.config = config_add

property from_scoping.id: int#

This property returns the unique ID associated with the operator. This property is lazily initialized.

Returns:: The unique identifier of the operator.
Return type:: int

Notes

Property available with server’s version starting at 10.0.

property from_scoping.specification#

Returns the Specification (or documentation) of this Operator.

Return type:: Specification
