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)
