I am not getting the solution from the above posts you have given.  
The reason why I commented out the cell\_data field because there is no `Cell data: gmsh:physical, gmsh:geometrical` in my `mesh_from_file` because it is the Abaqus file, that data will be present in the GMSH mesh file.  
The other thing which I am not able to follow from the given post [Transitioning from mesh.xml to mesh.xdmf, from dolfin-convert to meshio - #104 by dokken](https://fenicsproject.discourse.group/t/transitioning-from-mesh-xml-to-mesh-xdmf-from-dolfin-convert-to-meshio/412/104)  
is `facet_data = mesh.cell_data_dict["gmsh:physical"]["line"]`, because this dictionary is empty in my case.  
I request you to please provide me the code if you have it in which the Abaqua mesh file is deal with and following line is worked successfully.

```auto
with XDMFFile("facet_mesh.xdmf") as infile:
    infile.read(mvc, "name_to_read")
mf = cpp.mesh.MeshFunctionSizet(mesh, mvc)

ds = Measure("ds", domain=mesh, subdomain_data=mf)

```

So that, I will be able to apply boundary conditions.  
Thanks in advance
