Hello,

I recommend you to use the coupled option in non conformal meshing and set the boundary conditions accordingly so that you can specify different materials for your required specific locations. For further understanding please refer this link 

6.6. Non-Conformal Meshes (ansys.com) . If you are not able to access it kindly refer this link Using Help with links (ansys.com). Hope this solves your problem.

Thanks
