Question about the thermal thin_wall

[funderal]

Hello everyone,
I've been exploring this code with a keen interest in solving thermoplastic problems. However, I've encountered a stumbling block while trying to work with the thin_wall. I'm facing a ModuleNotFoundError: as detailed below:
`
ModuleNotFoundError Traceback (most recent call last)
Cell In[1], line 10
7 import time
9 from jax_fem.generate_mesh import Mesh
---> 10 from jax_fem.core import FEM
11 from jax_fem.solver import solver
12 from jax_fem.utils import save_sol

ModuleNotFoundError: No module named 'jax_fem.core'
`
But I can't find the core file in jax-fem. I'm wondering if there's something I might miss. Any guidance or suggestions would be greatly appreciated!

I believe you are referring to an outdated example. Perhaps this newer one can be of some relevance to you. Also check this example for thermal-mechanical coupling.

Thank you for your answer，I made the appropriate changes based on the code you provided, however a new error was reported as follows:
`
TypeError Traceback (most recent call last)
Cell In[13], line 148
143 # if j > 10:
144 # exit()
147 if name == "main":
--> 148 ded_thin_wall()

Cell In[13], line 92, in ded_thin_wall()
90 dt = t[1] - t[0]
91 sol = full_sol[points_map_active]
---> 92 problem = Thermal(active_mesh, vec=vec, dim=dim, dirichlet_bc_info=[[],[],[]], neumann_bc_info=neumann_bc_info_laser_off,
93 additional_info=(sol, rho, Cp, dt, external_faces))
95 for j in range(num_laser_off):
96 print(f"\n############################################################")

TypeError: init() got an unexpected keyword argument 'neumann_bc_info'
`
How do I make the change?

I think you are using the old version of JAX-FEM (in the JAX-AM repo), which is discouraged. Please use the new version in this repo.

[funderal]

But I'm using jax version 0.4.23, jax-fem version 0.4.4, and jaxlib version 0.4.23, aren't these the latest versions?

[tianjuxue]

You are using the right JAX-FEM version, but I think you are referring to an old JAX-FEM example.

I saw "init() got an unexpected keyword argument 'neumann_bc_info'" - This seems to be from an old example.

Thanks, as per your suggestion I ran the code for quiet_element example. However, after running it for a long time I got the following error:
