I am trying to run Von Mises elasto-plasticity — FEniCSx Fracture Mechanics tutorial.
and I am getting this error
AttributeError: 'dolfinx.cpp.mesh.Topology' object has no attribute 'cell_type'
(My dolfinx version is : 0.7.1)
Can anyone help me resolve this issue?
As we are preparing DOLFINx to support mixed cell meshes,
dolfinx.cpp.mesh.Topology.cell_type has been renamed
dolfinx.cpp.mehs.Topology.cell_types to reflect that we might have multiple types of cells in a mesh. This returns a list of cells in the mesh (currently it is an array with one entry).
Thank you, Where can I find the documentation for
Thanks again; the following function from the specified tutorial still gives me back error after changing to cell_types
def interpolate_quadrature(ufl_expr, fem_func:fem.Function):
q_dim = fem_func.function_space._ufl_element.degree()
mesh = fem_func.ufl_function_space().mesh
basix_celltype = getattr(basix.CellType, mesh.topology.cell_type.name)
quadrature_points, weights = basix.make_quadrature(basix_celltype, q_dim)
map_c = mesh.topology.index_map(mesh.topology.dim)
num_cells = map_c.size_local + map_c.num_ghosts
cells = np.arange(0, num_cells, dtype=np.int32)
expr_expr = fem.Expression(ufl_expr, quadrature_points)
expr_eval = expr_expr.eval(cells)
fem_func.x.array[:] = expr_eval.flatten()[:]
Is there anything else that has been changed in this version?
Also is there a preferred version of dolfinx for this particular tutorial (Von Mises elasto-plasticity — FEniCSx Fracture Mechanics) ?
The FEniCSx Fracture mechanics uses an old version of FEniCSx (i think it is 0.6.0).
I cannot list everything that has changed.
See: Computational fracture mechanics examples with FEniCSx — FEniCSx Fracture Mechanics
