Download a multielement airfoil with a cell centered solution.

Originally downloaded from CFD General Notation System Example Files

loadbool, default: True

Load the dataset after downloading it when True. Set this to False and only the filename will be returned.

pyvista.MultiBlock | str

Structured, 4 blocks, 2D (2 planes in third dimension) multielement airfoil, with cell centered solution. If load is False, then the path of the example CGNS file is returned.


Plot the airfoil dataset. Merge the multi-block and then plot the airfoil’s "ViscosityEddy". Convert the cell data to point data as in this dataset, the solution is stored within the cells.

>>> from pyvista import examples
>>> import pyvista as pv
>>> dataset = examples.download_cgns_multi()
>>> ugrid = dataset.combine()
>>> ugrid = ugrid = ugrid.cell_data_to_point_data()
>>> ugrid.plot(
...     cmap='bwr',
...     scalars='ViscosityEddy',
...     zoom=4,
...     cpos='xz',
...     show_scalar_bar=False,
... )
