Optional[ndarray[Any, dtype[int32]]]

Examples

Create a new selection of keypoints [1, 5, 10]

>>> mapdl.geometry.keypoint_select([1, 5, 10])

Create a new selection of keypoints from 1 through 20

>>> mapdl.geometry.keypoint_select(range(1, 21))

Unselect keypoints 1 through 20

>>> mapdl.geometry.keypoint_select(range(1, 21), sel_type='U')

Append to an existing selection of keypoints

>>> mapdl.geometry.keypoint_select([1, 2, 3], sel_type='A')

Reselect from the existing selection of keypoints

>>> mapdl.geometry.keypoint_select([3, 4, 5], sel_type='R')

Select no keypoints

>>> mapdl.geometry.keypoint_select(None)

Select all keypoints

>>> mapdl.geometry.keypoint_select('ALL')
