Hello,
I am trying to follow the tutorial of
DOLFINx, but when I
got to
A [0,1]\times[0,1] mesh distributed among processes
from mpi4py import MPI
from dolfinx import mesh
domain = mesh.create_unit_square(
MPI.COMM_WORLD, 8, 8, mesh.CellType.quadrilateral)
, it showed the message
Traceback (most recent call last):
File "<string>", line 17, in __PYTHON_EL_eval
File "<string>", line 12, in <module>
File "<string>", line 1, in <module>
File "/usr/lib/python3.11/site-packages/dolfinx/mesh.py", line 417, in create_unit_square
return create_rectangle(comm, [np.array([0.0, 0.0]),
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/lib/python3.11/site-packages/dolfinx/mesh.py", line 392, in create_rectangle
return Mesh.from_cpp(mesh, domain)
^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/lib/python3.11/site-packages/dolfinx/mesh.py", line 58, in from_cpp
obj.__class__ = Mesh
^^^^^^^^^^^^^
TypeError: __class__ assignment: 'Mesh' object layout differs from 'dolfinx.cpp.mesh.Mesh'
How do I solve it? Thanks.
