pyvista.DataSetFilters.compute_boundary_mesh_quality

DataSetFilters.compute_boundary_mesh_quality(*, progress_bar=False)

Compute metrics on the boundary faces of a mesh.

The metrics that can be computed on the boundary faces of the mesh and are:

• Distance from cell center to face center

• Distance from cell center to face plane

• Angle of faces plane normal and cell center to face center vector

Parameters:

progress_barbool, default: False

Display a progress bar to indicate progress.

Returns:

pyvista.DataSet

Dataset with the computed metrics on the boundary faces of a mesh. cell_data as the "CellQuality" array.

Examples

>>> import pyvista as pv
>>> from pyvista import examples
>>> mesh = examples.download_can_crushed_vtu()
>>> cqual = mesh.compute_boundary_mesh_quality()
>>> plotter = pv.Plotter(shape=(2, 2))
>>> _ = plotter.add_mesh(mesh, show_edges=True)
>>> plotter.subplot(1, 0)
>>> _ = plotter.add_mesh(
...     cqual, scalars="DistanceFromCellCenterToFaceCenter"
... )
>>> plotter.subplot(0, 1)
>>> _ = plotter.add_mesh(
...     cqual, scalars="DistanceFromCellCenterToFacePlane"
... )
>>> plotter.subplot(1, 1)
>>> _ = plotter.add_mesh(
...     cqual,
...     scalars="AngleFaceNormalAndCellCenterToFaceCenterVector",
... )
>>> plotter.show()
