Plot a 1D dolfinx mesh¶

In [1]:

import dolfinx.mesh
import mpi4py.MPI

In [2]:

import viskex

Generate a mesh of the unit interval, divided into six cells.

In [3]:

interval = dolfinx.mesh.create_unit_interval(mpi4py.MPI.COMM_WORLD, 6)

Plot the mesh.

In [4]:

viskex.dolfinx.plot_mesh(interval)

An optional argument dim argument controls the dimension of the entities to plotted. By default, it is equal to the topological dimension. In this example, dim=1 plots cells of the mesh (i.e., intervals), while dim=0 plots vertices of the mesh.

In [5]:

viskex.dolfinx.plot_mesh(interval, dim=1)

In [6]:

viskex.dolfinx.plot_mesh(interval, dim=0)
