This tutorial is part of viskex.

Creating subplots with pyvista

import dolfinx.mesh
import mpi4py.MPI
import pyvista

import viskex

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

cube = dolfinx.mesh.create_unit_cube(mpi4py.MPI.COMM_WORLD, 6, 6, 6)

Create plotters for each topological dimension using the lower level viskex.DolfinxPlotter class instead of the viskex.dolfinx functions. Pass a common pyvista.Plotter to the viskex plot function. Do not show each plotter yet.

plotter = pyvista.Plotter(shape=(2, 2))

for row in range(2):
    for col in range(2):
        plotter.subplot(row, col)
        viskex.DolfinxPlotter.plot_mesh(cube, dim=3 - row * 2 - col, plotter=plotter)

Finally, link cameras together and show the plot with subplots.

plotter.link_views()
plotter.show()
