pyvista.DataObject.add_field_data

DataObject.add_field_data(array: NumpyArray[float], name: str, deep: bool = True)

Add field data.

Use field data when size of the data you wish to associate with the dataset does not match the number of points or cells of the dataset.

Parameters:

arraysequence

Array of data to add to the dataset as a field array.

namestr

Name to assign the field array.

deepbool, default: True

Perform a deep copy of the data when adding it to the dataset.

Examples

Add field data to a PolyData dataset.

>>> import pyvista as pv
>>> import numpy as np
>>> mesh = pv.Sphere()
>>> mesh.add_field_data(np.arange(10), 'my-field-data')
>>> mesh['my-field-data']
pyvista_ndarray([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])

Add field data to a ImageData dataset.

>>> mesh = pv.ImageData(dimensions=(2, 2, 1))
>>> mesh.add_field_data(
...     ['I could', 'write', 'notes', 'here'], 'my-field-data'
... )
>>> mesh['my-field-data']
pyvista_ndarray(['I could', 'write', 'notes', 'here'], dtype='<U7')

Add field data to a MultiBlock dataset.

>>> blocks = pv.MultiBlock()
>>> blocks.append(pv.Sphere())
>>> blocks["cube"] = pv.Cube(center=(0, 0, -1))
>>> blocks.add_field_data([1, 2, 3], 'my-field-data')
>>> blocks.field_data['my-field-data']
pyvista_ndarray([1, 2, 3])
