While i was trying to run the demo_poisson.py
on the DOLFINx 0.3.1.0 documentation, i encountered the following error:
File “/mnt/d/Users/Desktop/demo_poisson.py”, line 25, in
cell_type=mesh.CellType.triangle)
AttributeError: module ‘dolfinx.mesh’ has no attribute ‘CellType’
Code, where the error to be found:
import numpy as np
import ufl
from dolfinx import fem, io, mesh, plot
from ufl import ds, dx, grad, inner
from mpi4py import MPI
from petsc4py.PETSc import ScalarType
#Create Mesh and FunctionSpace V :
msh = mesh.create_mesh(comm=MPI.COMM_WORLD,
points=((0.0, 0.0), (1.0, 1.0)), n=(32, 32),
cell_type=mesh.CellType.triangle)
V = fem.FunctionSpace(msh, ("Lagrange", 1))
my question is: after looking in the reference documentation (2022) of Dolfinx, i find the same declaration methode for the mesh class function (Attribute) CellType. Is there another way (update or so.) to to define CellType in Python?
PS: I’m using pip and not docker. (Debian/Ubuntu packages)Preformatted text
