# Read FEniCS/Dolfin Meshes
# =========================

# PyVista leverages meshio to read many mesh formats not natively supported
# by VTK including the FEniCS/Dolfin XML format.
# This example uses `pyvista.read()`.
import pyvista as pv
from pyvista import examples

# Let's download an example FEniCS/Dolfin mesh from our example data
# repository. This will download an XML Dolfin mesh and save it to PyVista's
# data directory.
saved_file = examples.download_file('dolfin_fine.xml')
print(saved_file)

# As shown, we now have an XML Dolfin mesh save locally. This filename can be
# passed directly to PyVista's `pyvista.read()` method to be read into
# a PyVista mesh.
dolfin = pv.read(saved_file)
dolfin

# Now we can work on and plot that Dolfin mesh.
qual = dolfin.cell_quality()
qual.plot(show_edges=True, cpos='xy')
