I am currently modelling a BRB member. And I tried to connect nodes between core and tube by using axial connector. This requires me to add wire features between the nodes of core and tube. I tried to modify the input file and import the file. However, it shows that the mesh is invalid and the warning messages below：
Warning: Permission was denied for "abaqus.rpy"; "abaqus.rpy.948" will be used for this session's replay file.
The model "BRB_Modified" has been created.
WARNING: Empty part CORE. This occurred while reading keyword options within part definition.
WARNING: Empty part TUBE. This occurred while reading keyword options within part definition.
WARNING: Part instance CORE-1 references an empty part. A new part named CORE-1 will be created from the mesh data in part instance CORE-1.
The part "CORE-1" has been imported from the input file.
WARNING: Part instance TUBE-1 references an empty part. A new part named TUBE-1 will be created from the mesh data in part instance TUBE-1.
The part "TUBE-1" has been imported from the input file.
WARNING: Node-based surfaces are not yet supported in Abaqus/CAE. The following node sets have been created in place of the corresponding node-based surfaces so they can be used in Abaqus/CAE.

The section "ConnProp-2_CONNSECT-1" has been assigned to 1 wire or attachment line.
The interaction property "INTPROP-1" has been created.
Warning: Mesh sets or surfaces have been invalidated due to changes to the mesh.
WARNING: The following keywords/parameters are not yet supported by the input file reader:
If CAE cannot read your input file completely, you probably cannot import it.
I suggest to do all the steps you need to do in CAE first, write and edit the input (adding all those connectors), and then run the input file directly from the command line
abaqus job=...
(How to do this depends on whether you are under windows or Linux.)
