Generate a mesh of the unit interval, divided into six cells.
interval = dolfinx.mesh.create_unit_interval(mpi4py.MPI.COMM_WORLD, 6)
Plot the mesh.
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.
viskex.dolfinx.plot_mesh(interval, dim=1)
viskex.dolfinx.plot_mesh(interval, dim=0)
