Read FEniCS/Dolfin Meshes#
PyVista leverages meshio to read many mesh formats not natively supported by VTK including the FEniCS/Dolfin XML format.
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.downloads._download_file("dolfin_fine.xml")
print(saved_file)
Out:
/home/runner/.local/share/pyvista/examples/dolfin_fine.xml
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 do stuff with that Dolfin mesh!
qual = dolfin.compute_cell_quality()
qual.plot(show_edges=True, cpos="xy")
