Error when trying tutorial examples

1

When I run the Helmholtz complex problem examples in the dolfinx, the result is ModuleNotFoundError: No module named ‘mesh_generation’. And run import dolfinx
print(dolfinx.version, dolfinx.git_commit_hash), the result is 0.5.1 74facfc3a587be94a8936bec0aece8b79d92f62e. I don’t know what’s wrong .
I am looking forward to recieve response. Thank you very much!

And the example can be found through The Helmholtz equation — FEniCS 22 tutorial (jorgensd.github.io).

You need to download the mesh_generation script from fenics22-tutorial/mesh_generation.py at main · jorgensd/fenics22-tutorial · GitHub
