ExplicitStructuredGrid.cell_coords

ExplicitStructuredGrid.cell_coords(ind: int | VectorLike[int]) → None | MatrixLike[int]

Return the cell structured coordinates.

The cell structured coordinates are the (i, j, k) index of a cell along the grid’s three structured axes, with (0, 0, 0) being the first cell. This method is the inverse of cell_id(), mapping a flat cell ID back to its structured coordinates.

Parameters:

indint | VectorLike[int]

Cell IDs.

Returns:

outputnumpy.ndarray | None

Cell structured coordinates. None if ind is outside the grid extent.

pyvista.ExplicitStructuredGrid.cell_id

Return the cell ID.

Examples

>>> from pyvista import examples
>>> grid = examples.load_explicit_structured()
>>> grid.cell_coords(19)
array([3, 4, 0])

>>> grid.cell_coords((19, 31, 41, 54))
array([[3, 4, 0],
       [3, 2, 1],
       [1, 0, 2],
       [2, 3, 2]])
