pyvista.examples.cells.QuadraticHexahedron#

QuadraticHexahedron() → UnstructuredGrid[source]#

Create a pyvista.UnstructuredGrid containing a single quadratic hexahedron.

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

Returns:
pyvista.UnstructuredGrid

UnstructuredGrid containing a single quadratic hexahedron.

Examples

Create and plot a single quadratic hexahedron.

>>> from pyvista import examples
>>> grid = examples.cells.QuadraticHexahedron()
>>> examples.plot_cell(grid)

List the grid’s cells.

>>> grid.cells
array([20,  0,  1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11, 12, 13, 14, 15,
       16, 17, 18, 19])

List the grid’s points.
