pyvista.UnstructuredGrid.offset#

property UnstructuredGrid.offset: NumpyArray[float][source]#

Return the cell locations array.

This is the location of the start of each cell in cell_connectivity.

Returns:

numpy.ndarray: Array of cell offsets indicating the start of each cell.

Notes

The array returned is immutable and cannot be written to. If you need to modify this array, create a copy of it using numpy.copy().

Examples

Return the cell offset array. Since this mesh is composed of all hexahedral cells, note how each cell starts at 8 greater than the prior cell.
