pyvista.examples.cells.QuadraticQuadrilateral

QuadraticQuadrilateral() → UnstructuredGrid

Create a pyvista.UnstructuredGrid containing a single quadratic quadrilateral.

This cell corresponds to the pyvista.CellType.QUADRATIC_QUAD cell type.

Returns:

pyvista.UnstructuredGrid

UnstructuredGrid containing a single quadratic quadrilateral.

Examples

Create and plot a single quadratic quadrilateral.

>>> from pyvista import examples
>>> grid = examples.cells.QuadraticQuadrilateral()
>>> examples.plot_cell(grid, cpos='xy')

List the grid’s cells.

>>> grid.cells
array([8, 0, 1, 2, 3, 4, 5, 6, 7])

List the grid’s points.

>>> grid.points
pyvista_ndarray([[0. , 0. , 0. ],
                 [1. , 0. , 0. ],
                 [1. , 1. , 0. ],
                 [0. , 1. , 0. ],
                 [0.5, 0. , 0. ],
                 [1. , 0.5, 0. ],
                 [0.5, 1. , 0. ],
                 [0. , 0.5, 0. ]])

>>> grid.celltypes  # same as pyvista.CellType.QUADRATIC_QUAD
array([23], dtype=uint8)
