Providing keyword arguments to the pyvista plotter

import dolfinx.mesh
import mpi4py.MPI

import viskex

Generate a mesh of the unit square by dividing each edge of the square in 6 segments.

square = dolfinx.mesh.create_unit_square(mpi4py.MPI.COMM_WORLD, 6, 6)

Each plotting function accepts optional keyword arguments, that are passed directly to the add_mesh method of the underlying pyvista plotter. For instance, the following two notebook cells plot the mesh using pyvista default color (red) first, and then using a custom color provided as a keyword argument (blue).

viskex.dolfinx.plot_mesh(square)
