Examples
Here we create a single node and interrogate its selection status.
>>> from ansys.mapdl.core import launch_mapdl >>> from ansys.mapdl.core.inline_functions import Query >>> mapdl = launch_mapdl() >>> mapdl.prep7() >>> n1 = mapdl.n(1, 0, 0, 0) >>> n1 1
We can use
Query.nsel
to interrogate the selection status of the node. The response is anenum.IntEnum
object. If you query a node that does not exist, it will return a statusSelectionStatus.UNDEFINED
.>>> q = Query(mapdl) >>> q.nsel(n1) <SelectionStatus.SELECTED: 1> >>> mapdl.nsel('NONE') >>> q.nsel(n1) <SelectionStatus.UNSELECTED: -1> >>> q.nsel(0) <SelectionStatus.UNDEFINED: 0>
